I've no problem with that, but if V2 is ported to Python, there will be little
from bjam left. The Jam syntax parser is good enough, and I'm sure you won't
like to touch either variable expansion code, or build engine itself ;-) It's
a bit scary.

BTW, can you clarify? I believe that problem now is that free requiremets are
not propagated from exes to PCH targets.

Where will that values come from? In any case, this does not sound like
radical change from the current model, it's just additional customization
