--- Comment #2 from Chris Hennick <christopherhe at trentu dot ca> ---
Shouldn't it at least raise a warning, even using the default invocation? To
me, a positive sizeof(x) implies that x is an object that can be moved and
copied, and from what I've read, some novice programmers seem to expect that to
be true for compiled and loaded functions.

Of course, an alternative would be to actually compile/link all sizeof'd
functions in such a way that they *could* be moved and copied...
