fyi:
In mkiv the principle is the same but it's a bit more more dynamic:
\namespaceinstance:key
with namespace being efficiently shortcut deep down in context. The new
fashion is then \namespaceparameter{key} given that
\currentnamespace == instance is set. This is the new commandhandler
approach that we use in overhauled core code as well as in Wolfgangs and

compensated by way less hash entries and other speedups in the overhaul.

Fair enough. I got it to work now with,
\startitemize[R,2*broad][start=11,before=\startlinecorrection,after=
\stoplinecorrection]
My only concern here is that, for something as incredibly fundamental
and recurring in the world of ConTeXt, the caveats and distinctions to
be made between options and assignments, that can and have taken down
entire operating systems, or cause hour after hour of no end of vague
syntactical errors, or even successful compilations with the wrong
effects, shouldn't that probably have been mentioned at least once, even
if only in passing, somewhere within the 369 page user manual? The word
assignment I couldn't locate once.
You’re right, it can cause confusion to people migrating from
Latex where package options, afair, allows mixed key-value/list
syntax (like e.g. Lua does as well). Random example from the
KOMA-Script manual:
\documentclass[BCOR=12mm,DIV=calc,twoside]{scrartcl}
^ ^^^
assignment … switch
Therefore the difference to Context deserves mention at least
somewhere in
http://wiki.contextgarden.net/From_LaTeX_to_ConTeXt
which said migrators are most likely to consult first.
- Maybe it could be more explicit, but if you ever take a look at
documentation, for example
http://wiki.contextgarden.net/Command/setupitemgroup
you will notice that some brackets are depicted with [...,...] and
others with [...,...=...,...]
And while we are handing out reading assignments (pun intended)
here are two wiki links that provide background information:
http://wiki.contextgarden.net/System_Macros/Comma_Separated_Lists
http://wiki.contextgarden.net/System_Macros/Key_Value_Assignments
Perhaps it makes most sense to think of Comma Lists v. Assignment
Lists in terms of the two different argument parsers being used
to process them.

Thanks Philipp. I'm finding that one of the big weaknesses of ConTeXt is
similar to a common criticism of the first one listed on Git here:
https://steveko.wordpress.com/2012/02/24/10-things-i-hate-about-git/
It requires users to know too much about how ConTeXt actually works
internally (e.g. its information model). Maybe this is necessary. Maybe
it isn't. I'm fairly new to typesetting and never came from a background
of decades of experience with TeX. But it seems to me like any
programming language, and ConTeXt is a kind of one for document
engineering, should have users focusing on creating beautiful books and
not on the language's information and processing model.
Just my two cents.

Hey Wolfgang,
The good news is that this is probably what I need. The bad news is
luatex completely blows itself to pieces, allocating memory until the
system crashes.
After much grinding of the machine, I managed to finally SIGSTOP and
attach gdb to the naughty process.
I've cc'd the luatex user mailing list since this is probably, I
suppose, a luatex issue more than a ConTeXt one.
I am using luatex beta-0.71.0-2012030522 (rev 4364) through context
version 2012.03.13 21:26 on amd64 hardware running Ubuntu Maverick.
One other thing that I should have made more clear, this only happens
when I insert the aforementioned line correction commands.
Make a example because this works:
\starttext
%\dorecurse{2}{\input tufte\par}
\dorecurse{3}{\input tufte\par}
\startitemize[before={\startlinecorrection[blank]},after=\stoplinecorrection]
\dorecurse{4}{\startitem \input ward \stopitem}

The problem is the empty second argument.
\startitemize[before=\startlinecorrection,after=\stoplinecorrection][]
When you pass two arguments with \startitemize the first argument os for
keywords (e.g. packed or fit)
and second argument is for assignments (e.g. width=3cm) in your case context is
looking for the keywords
“before=\startlinecorrection” and “after=\stoplinecorrection” which results in
a loop.

Hey Wolfgang,
The good news is that this is probably what I need. The bad news is
luatex completely blows itself to pieces, allocating memory until the
system crashes.
After much grinding of the machine, I managed to finally SIGSTOP and
attach gdb to the naughty process.
I've cc'd the luatex user mailing list since this is probably, I
suppose, a luatex issue more than a ConTeXt one.
I am using luatex beta-0.71.0-2012030522 (rev 4364) through context
version 2012.03.13 21:26 on amd64 hardware running Ubuntu Maverick.
