SixtyPical

SixtyPical is a very low-level programming language, similar to 6502 assembly, with static analysis through abstract interpretation.

In practice, this means it catches things like

• you forgot to clear carry before adding something to the accumulator
• a subroutine that you call trashes a register you thought was preserved

and suchlike.

It is a work in progress, currently at the proof-of-concept stage.

The current version is 0.2-PRE. It is a complete reboot of SixtyPical 0.1. The reference implementation is written in Python instead of Haskell. The language is much simpler — we're going to try to get the analysis completely right before adding more sophisticated and useful features.
