OK. I don't know enough to tell whether this is a critical issue, but I can imagine situations where extensive recursion might be needed, which in turn would mean bigger stacks (and footprint) in normal procedural languages. > By looking at the Rhino code, it appears to me to be a lot of work to > modify it to have such support.

While there are many benefits in using a mature implementation, it might count even more to have total control over both the syntax and the implementation (and a dedicated programmer who knows these inside out ;) (: A ;) --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
