error parsing comma operator float c = (0.0, 1.0);

[AndrewRayCode]

I didn't realize this was valid glsl code, but apparently it is:

float c = (0.0, 1.0);

and it evaluates to the last statement.

So this fails:

console.log( deparse( parse( tokenize(` void main(void) { float c = (1.0, 2.0); }`) ) ) );

expected `)`, got `,` at line 4

Same with things like:

vec2 q = vec2((1.0, 2.0));
