This question came up in the pulls.
Given two different Tuple types, it is possible to run an
operator on said
tuples, if the operator is legal for each individual field in
the tuple.
For example.
Even if each field-wise operations is legal, the synthesis
operation of
individual results might not be obvious.

Hum...
I went to C++ to see how they do it. Apparently, in C++,
cross-tuple operations are fair game:
//----
#include <iostream>
#include <tuple>
int main()
{
std::tuple<int, int> a;
std::tuple<short, short> b;
a = b;
if (a == b)
std::cout << "hello" << std::endl;
if (a < b)
std::cout << "hello" << std::endl;
}
//----
If we follow the rule of "least surprise" and that "things which
are common behave the same", it might be safer to keep this
behavior.
