It's not a bug. The 'async' is part of the function signature, so the
function signatures don't match and it can't be converted.

It might be a missing feature, but I think it's preferable to explicitly
require the .begin.

Hm, the begin function returns a void, but that's what the signal expects
anyway, so it seems like that one should work. That would be a bug than.
