Alternatively, use a separate table as a self-generating cache instead of overloading the tooltip itself.

It does use tooltip to store, it's both a table and a widget and if you try tooltip[1234] and it doesn't exist, then it calls the function at __index to do a lookup and store the result string at that position, so next time you call tooltip[1234] it returns the string instead of doing a lookup. I refer to the tooltip object using "self" in the function, it's the same object.
