Comment:
There is a test in `doc/en/developer/coding_basics.rst` that uses
`Integer.powermod_ui` as an example for difference behavior for 32 bits
and 64 bits. Do you have an other example in mind?

Right. On the previous version we had
{{{
sage: type(binomial(5r,2r))
<type 'int'>
sage: type(binomial(5r,2))
<type 'sage.rings.integer.Integer'>
sage: type(binomial(5,2r))
<type 'sage.rings.integer.Integer'>
}}}
I will change that.
