I was to say that when it’s about simple enough things, there’s a way
people agree, especially if we try keeping it minimal, but then Stefan
Monnier proposed a different version of until I didn’t though about, so
I must admit this is more complex (I keep thinking we need different
words / identifiers for non-minimal cases).

If we’re effectively speaking of stuff big enough to justify a package,
then we’re going into DSL libraries that might make themselves alien and
less readable to the uninitiated.

I’m unsure, it encourages reinventing the wheel, while there are other
measurment to discriminate between what is known, common and popular and
the more experimental rest.
