Hi All,
Following Bart and Jonathan thoughts on the side effects of list
assignment....

Can anyone explain why these print different output?
my ($x,$y);
print $x++ , ++$x , $x++ ,"\n"; # prints 032
print $y++ . ++$y . $y++ ,"\n"; # prints 022
I was going to suggest that someone that the ++prefix was bugged only over
the "," operator until I saw this:
my ($x,$y);
print ++$x , ++$x , ++$x , ++$x , ++$x , ++$x ,"\n"; # prints 666666
print ++$y . ++$y . ++$y . ++$y . ++$y . ++$y ,"\n"; # prints 223456 (and
not 123456!)
Shouldn't the super-high precedence of ++ prevent there from being any
distinction between the "." and the "," operator?
