 Sorry for confusion, I meant that `lexTokens` only checks for eof/errors
 and
 calls an appropriate action to create token, but does not really directly
 inspect the input (it just uses `alexScanUser`). And that's why I don't
 think it
 is the right place to put some special case for closing the pragma.

 Anyway, I guess the best thing right now is to wait for some GHC dev to
 have a
 look at this.
