Leaving scopes is easy. You just walk up the stack and deconstruct things.
(Or, in this case, potentially run the end-of-scope code attached to each
scope)

I'm not seeing the problems with explicit scope management. Something's got
to set up and tear down the various scopes, after all. Explicit management
is a bit of a pain for the compiler, granted, but it gives us a lot of
flexibility we wouldn't otherwise have.
