Hi Niko,

I tried Phexample in Squeak and things work great. I had to load in
Regex-Core, but that's no biggie. I'll try my hand at editing the
ConfigurationOf and send you a patch.

I have only one blip: ForExampleStack >> #shouldFailWhenPopEmpty fails
because instead of 'this collection is empty' the example fails with
'this stack is empty'.

I'm not sure how to fix that, given that it's not your problem. One
easy way to get a green bar would be to change the error message in
Squeak (making it less accurate).

Any thoughts?
