There are two things here. First, because you've done ::NAME = (instead of
NAME=) this has set the constant at the top level: you've created
Object::NAME, not GG::GG::NAME
The second thing is that constant lookup always looks at the current
scoping before it starts walking up the lexical scope chain or the ancestry
chain: even after you include GG, GG::NAME is referring to the top level GG
(i.e. the module not the class)
