Hm, I agree that the type could be deduced. I could nevertheless
have sworn that this should be invalid:
..........................
template <typename T> int cmp1(T a, T b);
int (*cmp)(int, int) = cmp1;
...........................
But it compiles in fact.

I had no idea a template name could be implicitly instantiated in this
context. Thanks for educating me!
