Yes, you are right. And performance is no issue here, because
the fallback search is only done if the first one failed.

I Guess I'm getting enthousiastic about this idea. The only thing
that needs to be verified if Tcl modules still work: Will
a "package require foobar" find the file FooBar-1.0.0.tm?
