should this fix be applied to pharo? http://code.google.com/p/pharo/issues/detail?id=2655
Yes please. Almost everything I'm likely to put in Compiler, Kernel or System on Squeak 4.1 belongs in all dialects using the closure compiler.
Is there a dependency?
What's happing here is that very old primitive failure code that allowed the closure system to run on old VMs without closure support depended on BlockClosure>>asContext, which had a bug in it. So the changes reflect the bug fix but are enclosed in false ifTrue: [] because they really are obsolete, but the code is retained because its useful documentation of how the closure primitives should work. I hope this makes sense! best Eliot
