That's an example of a very common pattern of alternate constructors.

The other Chris' comment was:

zip.shortest(...) # same as zip(...) / zip.longest(...) / zip.checksame(...)
I kind of like this -- is there any precedent for it in the standard library?

If it's a very common pattern, do you know of any in the standard library beyond the one I mentioned? Not about bikeshedding the spelling of the different constructors, but just:

1. A callable;

2. That has one or more functions attached to perform some variation on what that callable itself does.

The dead increasingly dominate and strangle both the living and the

the lives and control the thoughts of homo faber. Ideas, once born,
become abortifacients against new conceptions.
