Oh I forgot to mention, in the Git project we don't allow declarations
to be mixed with code. Apparently there's some ancient compiler
somewhere that doesn't allow it. Declarations always have to be
together, at the top of a block. (Compile with
`-Werror=declaration-after-statement` to detect this.)
