module Foo
class String
def hi
puts ‘hi’
end
end
end
include Foo
x = “hello”
x.hi
Why does this not work?
Thanks.

You are defining a new class, Foo::String.
Try this here instead:
class ::String
The :: means ‘look up String in the global scope’.

A module is a namespace, so constant names defined inside a module are
nested within the module.
You’ve defined a new class named Foo::String which is not the same
class as String (a.k.a. ::String)

Is there some equivalent of a variable constant? I’m looking for a
variable that is shared only within the module but is variable.
Basically, a more restrictive global.
