I agree that this is the type of thing that declare() was setup for, however
I think there's value in keeping the same semantics as C for this feature.
This particular feature is a little unique in that it's (A) not a BC
breaking piece of syntax (older versions just see a comment), and (B) Having
the directive skipped (as a comment) doesn't impact code flow or the
resulting output.
I'd personally rather see:
#line "foo.re" 123
style syntax, but don't see a major problem with using:
declare(file="foo.re" line=123);
Just my 2 cents;
