This is like saying "my programming model is unable to describe the
reality accurately, so let's change the reality to make it fit the
model".

For me this is simply a shortcoming in the traditional single-dispatched
OO way of thinking, that it can't make the meaning of == depend on the
types of both arguments.

I don't say that the language should enforce == to be symmetric. I say
that the language should allow to define a symmetric == with the desired
meaning.

So I'm a fan of generic functions. Unfortunately they don't quite fit
Ruby (or Ruby doesn't quite fit my programming model) - I don't know if
emulating them in Ruby is worth the effort.
