The closure *is* the environment.

Are you familiar with local variables allocated on a stack? Then instead 
imagine stack frames allocated out of the heap, in a linked list. 
Instead of being deallocated at the end of a function, they are 
garbage-collected when there are no more references to them, just like 
any other object.
