Done. Thanks for the for #17920' model.
I ended up not using `integer_or_infinity`: here I prefer to not
accept both `-oo` and `+oo` when only one makes sense, and having two
functions (or one with parameters) seemed like overkill. This is
explicit and simple enough:
{{{
self._max_length = ZZ(max_length) if max_length != Infinity else
max_length
}}}
Cheers,
Nicolas
