Shouldn't non-const SEL references still work?
Message would be:
t.mm:11:30: error: non-const lvalue reference to type 'SEL' cannot
bind to a temporary of type 'SEL'
[self respondsToSelector:@selector(setPriority:)];
^~~~~~~~~~~~~~~~~~~~~~~
It is not an lvalue, it cannot be passed by reference.
Message is coming out of c++ side. Presumably no different that:
void foo(int&);
int main()
{
foo(10);
}
