Sure, why not.

A callable table, i.e. one with a __call metamethod:

http://lua-users.org/wiki/FuncTables

It happens that I'm currently using a callable table, but the one other function I have in the table I'm OK to get rid of. So I can switch it to a function instead of a table. I am sort of asking if that's OK, nothing will break because it's a function instead of a table. I guess I'm good to go?
