If he makes the type inferencer "proud", that might help alleviate
the fears around here that it will become standard practice to put
type annotations on everything. That is, if you explicitly annotate
a function in the same way that the inferencer would have inferenced
it, the PyChecker thingie would emit a message saying:

"I'm no dummy! I could have told you that foo() takes an 'int' and
returns a 'bool'. What do you think I am, stupid? Duuu-uhhh!"
