Recycling Tables, is it a good idea?

[MuffinManKen]

I thought I'd recently read something about whether recycling tables in lua was a good idea or not, but despite a lot of searching I couldn't find it.

I'm maintaining an addon that has table recycling, and if it really is a performance improvement then I'm okay with leaving it, but otherwise I prefer simple code.

What is the current state of this practice?
