Lua's own APIs use string literals for constant 'enum' values. Some examples
of functions that do this are collectgarbage, select, type, io.type,
io.open, and coroutine.status (there are several more.)

IMO it's quite an acceptable idiom in Lua code. LÖVE[1] uses string literals
for all of its many 'enum' constants.
