Subject: Re: Prevent ruby constant variables from changing?

Class names are strings.

The name of an anonymous class is an empty string.

The first time a class is assigned to a constant gets its name from
the constant identifier.

That happens automatically behind the scenes the first time you say class Foo.

Once a class gets its name the container where the class object lives
is irrelevant, the name is set in stone.

Normally constant User holds a class named "User", but technically it
could store a class named "Project".

Apart from those rules, constants and class objects are kind of
decoupled because they are just basic pieces of Ruby put together.
