No.  You're absolutely right that this was a useless, contrived
example; however, I think the point still comes across.  Sometimes you
need to initialize a local variable before you use it a block.  In
that case I still contend that 'returning' is more readable than the
initialize/mutate/return pattern.

This is a pattern that should be extracted; basically it's inject w/o
the iteration component.
