Well, that's the right thing to do, or else cast your int argument to one of
type 'test' -- tmp( (test) 1);

I often find people using enum types just so they can give fancy names to
integer values.  Instead, it's probably just as easy to use #defines, which
look the same, but only give type warnings if something's *really* wrong.
(such as using a #define with a string argument where an integer is
expected.)
