As it turns out, most of the material in this section has

already been checked in the process of checking out

everything else, and the section at this point is somewhat

anticlimactic. For this reason, we restrict ourselves

to testing two features not already covered.

Compound statements are delimited by braces. They have the

nice property that identifiers of the auto and register

variety are pushed and popped. It is currently legal to

transfer into a block, but we wont...
