--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- This warning would also help with this horror: https://twitter.com/zygoloid/status/1367301323838812160 #include <stdio.h> void f(float&&) { puts("float"); } void f(int&&) { puts("int"); } template<typename T> void g(T x) { f(x); } int main() { g(1.0f); g(2); } Prints "int\nfloat\n" because f(x) cannot bind directly to an rvalue reference so there is an implicit conversion.
