Thanks for that. Very detailed.
In terms of a use case, we just added a center function to mir
[1]. It can take an alias to a function. I wanted to add a check
that the arity of the function was 1, but it turned out that I
couldn't do that for mean [2] because it has a similar structure
as what I posted and arity relies on isCallable, which depends on
isFunction.
