So it seems to be essential point. But because we already have
the same problem with UFCS, I don't see why we should prohibit
external overloading of operator, it is just inequality (in
political sense) for operators :)
I'm not sure that it's fundamentally different from issues that
can affect other functions. I seem to remember running into some
issues along these lines when I tried defining math functions
(e.g. `cos`) to work with an `Imaginary` type I was trying to add
to `std.complex`.
If you're writing generic math code and you want to take the
cosine of a number whose type is not explicitly known, how do you
know which `cos` to use?
