This advice, unfortunately, needs to be tempered with caution about
namespace pollution and accidental dependency of things outside
unittests on things inside a version(unittest) block.  There's also the
issue of library code introducing extraneous import dependencies that
are really only necessary for unittesting, but get pulled in anyway
because user code happens to compile with -unittest.
