Thanks Brian,
The single line evaluation will be usefull in my purpose built DSL,
I'm essentially trying to build an iterative execution structure on top of a
recusive context-free one.
Too complex to explain in a couple lines, and still not all clear to me...
so the code I pasted is only an example, my project is all built using
classes and more cleanly scoped variables.

L-P
