Thanks.

Let's leave it in for now - once we have the tests, I can review this more in
detail, and we can evaluate better what the best approach may be.  If adding
support for absolute paths in the module component, then we will have to rework
more in the lexer to support that without side-effects.  If using library path
turns out to be the best way to go after all, we can revive that.  But I won't
know until we have full tests and I can do a better review and make more
informed suggestions.
