For instance, you can use it to easily do:

template <class T> struct has_preincrement_operator : std::integral_constant {};

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.
