For instance, you can use it to easily do:
template <class T> struct has_preincrement_operator : std::integral_constant<bool, IS_VALID_EXPR((T) a, ++a)> {};
Hmm, actually this use doesn't seem to work, though I'm not sure why... I should have tested it in the browser before posting the sample. I'm pretty sure it fails due to a compile-bug but I'm not entirely certain.
I'm sure that lambda cannot be used in unevaluated context.
