Awesome! Thanks Mike. :)
If anyone is interested, it's a simple CLI debugger that's just a single file
to drop into your project. I started it because it sounded potentially fun, but
it's actually pretty functional now. Does all the basic functions I wanted:
step, next, continue, finish, print/eval, up, down, trace. Getting the
environment correct for the print command was tricky, but I think it should
always give you the correct local / upvalue / global value based on the scope.
Now it can do vararg expressions in LuaJIT easily too. \o/
