- Subject: A question of style for C module writers

I have a question of style. It's about using constants in modules.
Let's say we have a fictious C library libfoo that defines a preprocessor symbol INFO with a value of e.g. 42.
Then I write a Lua module foo which exposes libfoo's functionality to Lua. Should INFO be an integer constant in foo or rather a string that is looked up using luaL_checkoption()?
foo.somefunc(foo.INFO, 'test data')
foo.somefunc('info', 'test data')
It's probably only a question of style or taste, but what is your opininion (or remarks) on this?
