[boost] C++11 challenge: ASSERT_INVALID_EXPR

I don't know whether this is actually possible, but I was thinking today
that there might be a way to use the new SFINAE to detect errors in a
large class of invalid expressions without actually causing a hard
error, and thereby build an assertion that fails compilation when passed
a valid expression and passes for any invalid expression in the large
class mentioned above.

Any takers?
