It's not fully equivalent to moving it out of the function because once you pull it out you add a name to the outer namespace: nested functions are useful to keep namespaces tidy too.
So I'd like to have nested pure functions too.
pure int foo(int y) { return y + y; } // outer foo
pure void bar(int x) {
pure int foo(int y) { return y * y; }
return foo(x) * .foo(x);
}
Thank you,
