Hello Jerome:

Thanks for the notes on the bug report. I will prepare a report and post it.

I downloaded the basic image from squeak.org/download. I did not know how to
figure out whether the image has Block Closures so I did this:

#(a b c) do: [ :s | Transcript show: s] ......... and got "abc" in the

and this...

#(a b c) do: [:s | [Transcript show: s] fork] and got "c" in the
Transcript (from an example from the mailing list)

So two questions:
1. Why should adding "fork" to the code change the closure behaviour
2. There are BlockClosure and BlockClosureTest classes in the image, does
this qualify to be supporting full closure
