I'm fairly sure that macro is no good.  It seems pretty clear the 'var' 
symbol is getting mixed up with 'values' at least.  Also the conflict in 
binding contexts (need to bind to get to the values but want to creat a 
top-level definition) seems pretty tough (although I'm sure some syntax 
guru can figure something out probably using set!).

I think the useful macro is receive:
