An interesting optimization. Exactly what gets kept, then? I'm guessing it's the probably the array to hold the key references.

/me notes that this will only become a problem if you have lots of different lexicals that hold a lot of data - one after the other - which is probably not a common case, and easily avoided by undef'ing them as demonstrated above
