I expect that's a good part of the reason for letting it simmer for the
last few years. The current proposals aren't completely cooked yet.
There are a number of ways of doing dynamic type checking (not
static type checking, though.) All of them share the property of being
both difficult and ugly to some degree or other.
As far as type inference goes, look at Bicycle Repair Man. It does
a form of type inference to check whether various refactorings are
possible. While I'm certainly not prepared to channel Guido, I think
he's in favor of type inference, if it can be done cleanly, without a lot
of wierd surprises.
