Hi,

Per the manual [1], Closure::fromCallable() =E2=80=9Ccreates and returns =
a new anonymous function=E2=80=9D. I guess that this might not match =
your notion of =E2=80=9Canonymous function=E2=80=9D?

Therefore, I am asking for clarification: What practical distinction do =
you make between =E2=80=9Dan instance of Closure=E2=80=9D and =E2=80=9Can =
anonymous function=E2=80=9D, and why does this distinction matter?
