Comment:
Good point! I made the change and added a doctest to `call()` to
illustrate that the bug is fixed.
The change does give a speedup. The best case I found was running
{{{
sage: timeit('mputils.call(a.ei, 1.0r, parent=float)')
}}}
Before the old patch, I was getting about 87 micro seconds. With the new
patch, the best time I got was about 60 micro seconds.
