This certainly looks cleaner than the template hack, but it does not seem to work: implctstringparam.cpp: In function ‘void foo(const char*)’: implctstringparam.cpp:9: error: ‘s’ cannot appear in a constant-expression

The const std::string& s would most likely need to be static inorder for static assertion to work.

The value of s is only known at runtime, when the function is called: you cannot use it in a static_assert, which is evaluated at compile-time. A static_assert can only evaluate constant expressions.
