struct and array support?

[bhouston]

I was chatting with @unconed about using glsl-parser to handle the new structs and arrays that I using in a refactor of ThreeJS's lighting BRDFs. He said it wasn't supported by glsl-parser. Is that the case?

[heisters]

I am seeing some issues with structs, and would be interested to hear about support for them.

For instance, this parses:

struct Foo {
};

void main() {
  Bar baz;
}

And this parses:

struct Bar {
};

void main() {
  Bar baz = foo();
}

But this throws

struct Foo {
};

void main() {
  Bar baz = foo();
}
