Undef has been used for different semantics in too many other languages.
Perhaps changing the word "undef" to "deleted" would add clarity?
So we'd have:
t[i] = deleted
Thanks,

I like the idea of `table.undef(t, k)`. It's much clearer (it doesn't look like you're storing something in the table, and doesn't make `undef` look like a value) and will still compile in older versions (where the same function can be easily implemented), plus won't break scripts that happen to use `undef` as a name already.
If we weren't concerned about compatibility, I'd go with `delete t[k]` or `delete k in t`. Then you have the possibility of deleting other things, which could be a hint to the garbage collector.
