Comment (by jpflori):
I'm also lost now.
My problem is I don't feel we need to copy that map just to print it.
And I don't get the meaning of Simon point in comment:231.
What I understood is that Travis suggested to add an optional
`suppress_warning` option to the `_repr_` method of `Morphism` set to
`False` by default.
In the piece of code currently printing the boring warning, one would use
`%m._repr_(suppress_warning)` as we don't really care to print that the
map was using weak references.
@Simon is it this construction that you find clumsy?
