I'm not experienced enough to really reply to this, but:

Something sticks to an old (Collection) incarnation of X.
If you change your code like this:

| x |
x := OrderedCollection new.
x add: 'blue'.
x do: [:a | Transcript show: a; cr]

making x local to the running code, the problem goes away.

First I thought the doIt would stick to x but

Smalltalk forgetDoIts

didn't help either.

So now I'm as curious as you to a reply of someone who really knows
:-)


Cheers
