I'm looking to find a way to prevent new values from being entered

However, I can still insert values like:

  table.insert(days, "Frankday")

Any suggestions?

Thanks to Patrick and Luis for the suggestions. I think I am going to
replace table.insert(), and have it check the object metatable for an
"__insert" metamethod. I'll also add a "__remove" metamethod and check
it from the appropriate table functions.

Just as an FYI, I'll be using these metamethods to generate "type
safe" collections, and also to synchronize a Lua table with an
internal C vector.

Thanks again for the suggestions,
