Because ruby allows you to change things at will.  There are still other
ways to change a class other than the ways you have learned so far, for
instance a user can enter a name and you can add a method with that name
to a class.

Well based on that logic, then because assignment to variables is
typically done with method names that end in '=', you should wonder
whether there is a method named "Const::NEW_CONST=".

That's just the way it is.
