Anyone feel free to make a good example of a token parser in Pascal so I can
see how it looks. I never an actual good parser that understands syntax so I
don’t have any good examples to go by.

I think they added const. In the past I’ve seen using “let” but I don’t think
that’s a real const if that

Yeah I mistyped. We shouldn’t be redefining GLfloat though (I doubt it’s a
double in OpenGLES/WebGL either) so how does this (or other types) translate
for the parser?
