Unfortunately, it's not hard at all.  scalar.size returns 1.

Yeah, it's stupid I know.  I kick myself every time I come up against the same 
problem (about twice a week).

The .list .hash and .size vmethods are all being revamped for TT3 to do The 
More Right Thing.  But I daren't change them in TT2 for fearing of breaking 
things and having a lot more people kicking me.
