#step(state, stream) ⇒ Object

override [jneen] This override is required because AddmusicK has an extremely free-form macro system that doesn't "look like a function call" the same way that normal preproc macros do. They are quite literally arbitrary characters that pre-empt other tokens, in all states.

AddmusicK is technically even more lenient than this about where macros can show up, e.g. "F=v123" will attempt to substitute into $FF twice. Neither Ramekin nor this lexer support that.
