You can override the filename and line number to the lexer: 
https://dlang.org/spec/lex.html#special-token-sequence

vibe.d does this so when errors from the trans-piled diet files happen, 
they match (mostly) back to the diet file, not the source file where 
they are mixed in.

That's a good question. I would say it should say line 17 or line 6 
(preferably the latter). That may be considered a bug, I don't know.
