Type Hinting vs Type Checking and Preconditions

I don't use isinstance() and type() at all, nor am I testing the type
of all variables being passed into function.  What I'm arguing for here
is a semantic safety mechanism that is neither required, nor imposed.
Ultimately what it looks like what I'm proposing is a syntactic
shorthand for the adapt() proposal.  Which, if other developers have
called for, makes my need not so far fetched.
