Why private #binding?

[Intransition]

Why is #binding a private method? I end up doing a lot of this:

class Scope
def __binding__
binding
end
end

In order to setup a scope for ERB evaluation, among other uses.

Why is #binding a private method? I end up doing a lot of this:

=A0class Scope
=A0 =A0def __binding__
=A0 =A0 =A0binding
=A0 =A0end
=A0end

In order to setup a scope for ERB evaluation, among other uses.

I can think of two potential reasons.

1. Because binding exposes the internals of the receiver.

2. because if it were public then in a case like:


class A
def self.binding_of(b)
b.binding
end
end

A.binding_of("abc")

might well return a binding with self =3D=3D A, rather than the string,
because binding returns the bindings "at the point of call"

The latter one was the biggest reason for me.

Knowing you, I suspected that that was the case. It would be for me as we=
ll.
