What is your desired end goal or use for such a piece of software?
I don't know that such a thing could exist, though, since one does
not learn languages by context-free listening to that language being
spoken. One needs a lot of clues about what various structures in
the language do. I.e. I believe that no matter how much recorded
audio of people talking in another language I listened to, I would
not be able to learn that language.

How do you envision it being used by these people? If you just want
to validate, "yeah this looks like a valid script," then the "easy"
way is to plug the grammar into a tool meant for parsing and let it
do the work for you. Otherwise the first hitch I can think of would
be dealing with variable names, especially in languages where
variables don't need to be explicitly declared.

A translator tool would then need not only the input files but what
the desired outputs were, so to train it up in the first place you'd
have to feed it not only the inputs but also the expected outputs.

When I think back to learning Java or Python, I think the major things to learn with new languages are a general feel for "how is this used differently from C++" (say Python's lists and lambda functions), familiarity with the environment (switching from Visual Studio to whatever else), and getting to know the core libraries (that is what took me so long with Java). I'll try my luck with Colin Moock, then. Thanks! Enno. -- -- I never wanted to be famous.
