It gets rid of *most* of it. :-)

It just looks so un-intuitive in your code though.
If you are as anal as I am, you might prefer to use
UNDEFINE:

It's the DELVAR for the rest of us.

Hmm. A case for the Bottom Inspectors, perhaps (Viz, anyone?)

OK, I've read it, but I have only a vague idea of why:

tempvar = Size(Temporary(varname))
