#15329: Fix pushout of completed fields
------------------------+----------------------------
Reporter: SimonKing | Type: defect
Status: new | Priority: major
Milestone: sage-5.13 | Component: coercion
Resolution: | Report Upstream: N/A
------------------------+----------------------------
The aim is to fix the following problem.
{{{
sage: from sage.categories.pushout import pushout
sage: pushout(Qp(7),RLF)
Traceback (most recent call last):
...
RuntimeError: maximum recursion depth exceeded while calling a Python
object
}}}
This boils down to change how `CompletionFunctor` (which is a type of
construction functors used both for `RLF` and `Qp(7)`) commutes with other
construction functors. Currently, it commutes with the fraction field
functor ''and'' with other completion functors. But in fact it is simply
not true that construction functors commute.
