I didn't catch that either. I think if hints are to go in decorators,
then it's best to extend the decorator mechanism to allow arbitrary
@-typehint (str, int) -> bool
The @- would signify that the typehint function is to receive an AST as
its argument, rather than its callable. The AST would be the parse tree
for the rest of the line. Alternatively, it could get the line as a
string and parse it with appropriate functions from the ast module.
