I introduced a bug here (noticed by "Alec Mitchell").
The "marker" argument should have been "_marker=_marker".

No, because I never really met an "hasattr" bug (although
I acknowledge that it may happen).

We replace a small C-implemented function with a small Python one.
Although the Python function may be about 10 times slower,
the overall effect is almost surely negligible.
A higher risk comes from the fact that some Python packages may
rely on the broken "hasattr" behaviour. That's the reason why
the problem is not fixed in Python itself.
