The following code should not compile: int foo(int x) { return x; } template <typename T> concept bool C1 = requires (T x) { {foo(x)} -> int&; }; template <typename T> concept bool C2 = requires (T x) { {foo(x)} -> void; }; static_assert( C1<int> ); static_assert( C2<int> ); However this compiles just fine with r226884. ^ permalink raw reply [flat|nested] 4+ messages in thread
