2548 - teach 'print' to print integers

Still can't print non-integer numbers, so this is a bit hacky.

The big consequence is that you can't print literal characters anymore
because of our rules about how we pick which variant to statically
dispatch to. You have to save to a character variable first.

Maybe I can add an annotation to literals..
