This was the implementation in Modular Smalltalk if I remember correctly.
In plain Smalltalk you send a message named #msg and the lookup gives you a
compile method.
In Modular Smalltalk, there is an intermediary step: #msg -> #Namespace.msg ->
compile method
I see. What I do not see is how to achieve this without a cost at
runtime. Given that it should support imports. Without imports, SNs are
pretty much useless :-)

Hi
- having a class Selector that get evaluated into a symbol. You can then
achieved selector namespaces, which does not incur a cost at execution.
I do not understand the idea. Could you give an example?

I mused with a colleague about how I'd like to see "lexically scoped
monkey patching", and he pointed me to some guys that want to add that
to Ruby (http://timelessrepo.com/refinements-in-ruby). Note the
inspiration for their work: ClassBoxes!
(http://scg.unibe.ch/research/classboxes)
I remember reading the paper years ago, and started working through it
again now. Something that's not clear to me is this: does ClassBoxes
require VM-side changes? (Because it changes the method lookup, after
all, searching packages for methods before working up the inheritance
tree.) If so, how invasive are they? If not, do we have a ball-park
estimate of how much work it would be to update ClassBoxes to a more
recent Squeak/Pharo?
I'm more than happy to do the dogwork. I'd just like to know whether
I'm signing up for months of work or not.
Thanks!
