actually, saying that evaluation is in any fixed order is a bad idea. If you try the same code, but with 3 variables: 
sub printit{ print @_; }

my $var = 1;
&printit($var,$var++,$var);

you will get 212 - would you say now that evaluation starts from the middle?

what happens, I think, is that Perl takes the argument list, and applies any mutators (like ++) in there, before evaluating the rest.

As a general afterthought, having dependent arguments with mutators in a function call, or just in the same statement, sounds like a bad idea. For a start, you might introduce 2 mutators at the same time - which is likely to produce rubbish... how would you expect something like 
my $a = NumberObject->new(5);

print SumNumbers($a, $a->square_me(), $a->double_me());

to behave?
