Great.

After reading WebIDL spec I've understood that T[ ] is passed
by-reference and sequence<T> is passed by-value, which sounds possibly
less efficient and farther in principle than the C signature, any
reason to prefer sequence instead of array ?

Also is untyped "sequence" valid (and intended) for all uniform*v and
vertexAttrib*v signatures ?
I guess they should be "sequence<GLfloat>" or sequence<GLint>".

(here also, passing by-value may generate unwanted copies on some bindings ?)
