With an interpreter you would need to keep a global "interpreter" scope that, in the absence of bytecode, would probably require maintaining a sourcecode state in memory (the parser state) so you could modify it according to the next interpreter statement, output and recompile and relink the whole object again. Personally, I don't think it is worth it: given more time I would rather master felix. You know, until a few emails ago I did not know the 'static' option existed, which is what I wanted since felix 1.1.
