extract takes an array and merges it with the local symbol table.
Essentially the same thing locals() would do if it was actually
writable everywhere (as Steven points out it isn't).

If you ask me, this is an insanely bad idea and I have not a clue as
to why you'd actually want to do this, rather than just work with the
array.
