Overview
This is an implementation of 'POSIX bc'. It is based on Python classes generated by ANTLR.
Why Parrot bc
Self education. A fairly simple language but has symbols and subroutines. Test for decimal bignum libraries. A starting point for more interesting languages like R, GDL.
Vision
Do the code generation like bc -> PIL -> PIR Be compatible with Pirate and Pugs. Switch to Perl6 after Gary Evans has made a Perl6 backend for ANTLR.
