Stef, I had a look at the description of these fixes, but it does not look like
there is something related in it.
Eliot, the requested output is below.
But as far as I can see, it is identical. Have verified it also in the Squeak
4.1 image, all three produce the same bytecode.
Perhaps it not the compiler directly but some closure related code?
Thanks
Stefan
