I read that remark.

That's not an issue, those (deprecated)
sharedPools will stay forever. There is also
classPool for class variables; at the VM execution layer both of them 
should be
indistinguishable.

I care more about issues with classes that
actually use shared pools and may run into naming conflicts.

BTW: Wasn't there something like
"sharedConstants"? I can faintly remember such
a thing in Smalltalk/V (for MSDOS).

That being said, should we treat classes
imported from other environments as constants?
AFAIR: sharedPools create non-constant bindings.
This will only make a difference, when dealing
with non classes.

It's after 9pm, I am havering.
