It is not a technical reason so much as a visceral response. :-)

I suppose I write programs differently than most people, but I've never
had a need to define more than three required arguments in a program
EVER, as far as I can recall. I'm sure there is a reason for the 10-12 I
sometimes see in programs I haven't written, but I can't imagine what
that reason is. People who come to me with those kinds of programs are
always confused. I just assumed that was one of the reasons why. ;-)

Cheers,

David
