let's try again ;) In the light of discussion in Portland, which liked Marc's
idea of using std::decay in the unary common_type too, the below seems good
to go now, given that there are bad interactions with the front-end bug we
have got.
template<typename _Tp>
struct common_type<_Tp>
- { typedef _Tp type; };
+ { typedef typename decay<_Tp>::type type; };
(talking to myself)
I guess decay never has sfinae-type errors, so it doesn't matter whether
we have this typedef or derive from decay.
