We can do this in trunk today using a variant of Lawrence's original

uses no C++ features, though it weakens type checking by removing away
constness.
In the cxx-conversion branch, we can use overloads, which will DTRT
with const.
My question is, what do folks prefer?
a) The trunk patch today, using no C++ features.
b) Wait for the cxx-conversion variant?
Surely (check(t), t) also works, and also strt wrt const.
My concern with (check(t), t) is that it evaluates 't' twice. It may
not be a big deal, however. In which case, I'm OK with that alternative.
