Looking at some examples of a package I came across this type of behavior: function f(n) a = n x -> x^a end g = f(2) g.a # 2 Can someone point out where that is documented?

If I remember correctly his is an implementation detail of anonymous functions and thus intentially not documented.

Fields of an anonymous function?

that’s the part of the documentation I didn’t read
