Usage example

#include <crap/functional.d/comparatorsfortype.h>

int main()
{
 constexpr const static auto test1 = crap :: comparatorsForType <unsigned int> :: template lessEqual<42u, 101u>;
 constexpr const static auto test2 = crap :: comparatorsForType <unsigned int> :: template lessEqual<101u, 42u>;
 constexpr const static auto test3 = crap :: comparatorsForType <unsigned int> :: template lessEqual<42u, 42u>;

 static_assert(test1, "test1: 42 should be less than or equal to 101.");
 static_assert(!test2, "test2: 101 should not be neither less than nor equal to 42.");
 static_assert(test3, "test3: 42 should be less than or equal to 42.");
 return 0;
