<pre>This simple program shows the fail:
#include <utility>
void func() {}
int main() {
std::pair y{"hello", func};
}
'func' is deduced as a function type, not decayed to a function pointer type.
Similarly, the diagnostic message suggests that the string literal is deducing
as an array, rather than decaying to a pointer-to-element.
This same test compiles cleanly with gcc and Intel/EDG front ends in the online
compilers at Compiler Explorer:
