(let ((mk-adder (lambda (x) (lambda (y) (+ x y ... )

sub mk_adder { return sub { my $y = shift; $x + $y } }

but much cleaner (in Perl-land) as:
sub mk_adder { my $x = shift; return sub { my $y = shift; $x + $y } }

Hi all,
I noticed search.cpan is acting differently now (probably due to the HOOO
perl fiasco). Were these changes discussed anywhere publicly before they
were made? I'm interested in a full list of changes, so I don't have to
guess what they are. (I'm a /little/ upset since DBIC developer releases
are missing, modules I own in the modulelist are showing up as **
UNAUTHORIZED RELEASE **, modules are missing from search results,
different mirrors are behaving differently, etc.)
Also, I can't seem to find the search.cpan source. Could someone provide
a pointer to it?
search.cpan is not an official perl.org as such.
It's written and owned by Graham, and blessed with the domain name as
the best implementation of this functionality.
As for your unauthorized release, they are because you made unauthorized
releases :)
You released modules without getting permissions on all of the namespaces.
I suggest you rectify the problem and do an authorized release :)
The problem seems to have fixed itself. The module in question was
Test::WWW:::Selenium::Catalyst, which is the only module in the dist and was
registered to me in the modulelist... but it was only a developer release and
I had never uploaded a real release. Corner case...

This is two-fold situation.
The opposite of what you said is true - the purpose of my module is to
gain access to numerous LISP packages (maxima, etc) from Perl.
I don't like socket approach, I like inter-language operations.
But what you said is also true.
I will be using the module to bring the power to my LISP programs also,
something like
(perl5re string ([\d.]+))
to extract all the numbers from string.
Yet I like the combination of Perl+Lisp+Tcl/Tk thus providing rich GUI,
rich mathematical packages, rich CPAN.

It's everywhere offtopic :) because this is all new unfortunately (it
was surprise to me to find only toy LISP implementations on CPAN, and no
real Lisp connectors).
I wonder whether there will be enough followers, so for it to create
Perl+Lisp mailing list...
Thank you for your ideas, BTW.
Best regards,
Vadim.

I'm LISP novice (although met it some 15 years ago, now I'm more serious
with our relationship at our second attempt :) :)
so I can be easily wrong
but my vision of your BEGIN block is:
(eval-when :when-compile
(dolist (fname '(BUFFER CALLBACK ETCETERA))
(eval (read-from-string (format nil (defun ~A ()
(do-something-useful)) fname)
Why didn't you placed functions in AUTOLOAD, and creating them only when
needed?
My Tcl::Tk module do heavy usage of AUTOLOADing, you may want to look at
the approach :)
Initially I did eval $string but then come to safer approach.
PS. now this *is* off-topic, sorry for that.
I'll try to be more on-topic from now on :)

Not even close. `eval EXPR` burdens you with generating
syntactically correct code and moves everything from compile time
to runtime.
It’s like the difference between doing
*foo = sub { $bar };
and
my $_bar = quotemeta $bar;
eval sub foo { \$_bar\ };
`eval EXPR` is useful, but a poor substitute for solid
metaprogramming facilities.

Re: LISP module from CPAN
# from Vadim # on Wednesday 09 May 2007 10:53 am: Why didn't you placed functions in AUTOLOAD, and creating them only when needed? Because then you must override can() or your code is broken. It is usually a lot simpler (and gives better diagnostics) to just generate and install everything in advance. Particularly if you're only doing it to save typing. If you *actually* want to delay the decision of whether $foo-can(bar) until run-time, then yes autoload is the way to go. --Eric -- Time flies like an arrow, but fruit flies like a banana. --Groucho Marx --- http://scratchcomputing.com ---
Re: LISP module from CPAN
so if there were lisp-like macros available in perl, my sugar example
might be something like the following?
macro hashkeyaccessor(fieldname) { sub fieldname { $_[0]-{fieldname}} };
hashkeyaccessor $_ for qw/FIELD NAMES GO HERE .../;
and I would save the trickiness of getting the interpolation level
right. That is
imagining a CPP macro... the LISP idea on macros is that the template
would be created at the optree level rather than the source level, but its still
a template and replacement kind of deal. What am I missing?
