I think that's orthogonal to the question of what syntax to use for the regex.

Maybe we did over-relax the tests and should check more explicitly for
an optional calling convention attribute. Or maybe suppress them in
the TypePrinter. I believe there's a different thread for that
discussion though :)

Grepping for "expect.*\.\*" works for finding these ones.

Requiring -re on directives with regexes makes them easier to grep
for, but I don't know how important that is.
