The Cratera Programming Language (and support components)

This repo contains the Cratera to Lua compiler, as well as support components for the Cratera to Lua compiler, namely a pure-Lua Lua tokenizer and a table-based parser thing.

Cratera is a language very similar to Lua, and as such most of the Lua manual applies to it. Additionally, it supports the following syntax sugar, called "traits":

mytable:[mytrait].myfunction(myargument)

which is equivalent to:

mytable[mytrait].myfunction(mytable, myargument)

This syntax sugar is similar to the "methods" syntax sugar (Lua 5.3 §3.4.10, Lua 5.2 §3.4.9, Lua 5.1 §2.5.8), and, indeed, mytable is only evaluated once.
