Well, they were supposed to just be `if` and `switch` statements, the
two statements where an initializer was important. It was a focused
change for a specific problem; it wasn't supposed to metastasize.

The idea of proliferating statements into arbitrary expressions just
to contain the scope of some local seems... unpleasant. It'd be much
more reasonable if we just had a mechanism to explicitly end the scope
of an automatic variable.

Though you could just use `optional<T>` and reset it when you want to
terminate it.
