Nope, not really related. The engine may know about the source or
line number information--certainly if it wants to emit meaningful
error messages for the number chunk, or reparse the source for the
former. (On the off chance that something changes significantly
enough to warrant recompiling a segment of code) Debuggers might also
make some use of that, though I don't suppose they have to.

Arbitrary metadata? Nope, no plans for that. While I can see it as a
useful thing (though it wouldn't be unicode, at least unicode
wouldn't be required) I'm not sure it's worth the time to define,
implement, and maintain.
On the other hand, if someone has a good proposal, clean API, and
generally feels strongly about it I certainly won't have any
objections.
