The error message is not helpful at all. I was recently struggling to 
understand why/where some code was failing with syntax error – and it 
took me a while to find it. And with this message, I had also to find 
out what did go wrong.

How about: ("Unexpected junk after %s at %L", 
expr->n.symtree->sym->name, &expr->where)? – or "Unexpected junk in 
reference to %s at %L"?

Or deviating from your current error messages: ""Inconsistent use of %s 
at %L"

(Side note: I think we have the general problem that expr->where does 
not start after the white space, which can be slightly confusing.)

Cheers,
