But technically a long string takes longer to do the initial hash, 
right? So I can imagine a situation where a string must be interned at 
runtime (constructed on-the-fly) and where you might see some runtime 
performance issues for long strings vs. short strings.

With that said, Lua's string hashing function is awfully efficient, so I 
think you would have to come up with a pretty unrealistic example to 
notice the difference.
