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.

�

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!
