I never use the numpad, not even for numbers, it's too far away.

I meant, it's impossible to use them *without* their prefix: Even with
something like [import list] you couldn't use [abs] when you want to
get [list/abs], because [abs] is builtin.

Same for [list]-abs: I wouldn't recommend to use [list-abs/list-abs],
though it works.

Note that you're saying here that [counter] should be called without
"namespace", while [list/abs] should be called with "namespace". Maybe
talking about "namespaces" is just confusing and talking about plain
"names" for objects or classes would be clearer. Names must not
conflict, but building your non-conflicting names can be done in
several ways. Many involve using some kind of repeating prefix.
Whether that prefix is separated with a slash or a dash doesn't matter
