[antlr-interest] Example C style interpreter?

[Brian Todoroff]

Thanks.  That's more along the lines of what I was looking for.  It
appears that he basically takes the AST from ANTLR and writes his own
tree walker to evaluate the tree instead of using ANTLR to create the
execution walker.  That might be the better decision as it saves
keeping another copy of the grammar in sync and the tree parser has
already ensured a valid input stream, but I'll have to think on
that...

Thanks,
Brian
