Interesting example of a compiler to java (I like the idea of the
pipeline operator), but I'm really looking for an interpreter.
Something that takes the input code, creates the AST and actually runs
the code with function calls, loops, etc.
Doesn't need to be a fancy language and I don't care what language the
final interpreter code is in (C, C++, Java, C#, etc.).  I'm just
looking to get a feel for the design patterns around ANTLR based
interpreters for doing things like building up the function lookup
table and moving that between the parse and execute phases, handling
flow control constructs such as for, do, & while loops, etc.

Thanks,
Brian
