"static_assert(false)") still trigger errors. See the latter parts of the
constexpr if section here: https://en.cppreference.com/w/cpp/language/if

From what I could test on godbolt, using LLVM evrsions back to 5.0,
Clang does reject the "return ClientMain();" call you aren't seeing an
error on. So I'm not sure what compiler/version/situation you're
running, but at least at first blush it doesn't look like clang.

Hello,
In the below code the compiler throws "undeclared identifier" when the
commented line is uncommented. Whereas the line just before compiles fine.
Regards,
Manu
typedef bool (* DummyFunc) ();
bool ExecDummy (DummyFunc fptr) {
if (fptr)
return fptr ();
return false;
}
