Hello, clang (c++11 support) fails on code like:
BOOST_STATIC_ASSERT(( is_same< void, typename result_of< Fn() >::type >::value));
with error:
no type named 'type' in 'boost::result_of<void (&())(X &)>' is_same< void, typename result_of< Fn() >::type >::value)); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~**~~
Does Fn == void (&)(X&) or void (X&) ? I.e., is it a unary function type?
There might've been a recent change only for Clang to allow result_of to be better usable with SFINAE: result_of< F ( Args... ) > doesn't have a nested type typedef if F ( Args... ) is ill-formed (which appears to be the case here).
And the person who did that change didn't think of running the test?
My bad, I assumed this was a test from Boost, but this doesn't seem to be the case.
