Perl evaluates left to right

While it's certainly true that the short-circuit operators in Perl are left-to-right, which is what the OP mostly wanted to know at the moment, it might be saying to much to say that Perl evaluates left-to-right. It depends on your operators...

  print for map { $$_[0] } sort {
    lc $a->{name} cmp lc $b->{name}
  } grep { ref $_ } map {
    [$_, dblookup($_)]
  } <STDIN> unless grep {
    /--ignorestdin/
  } @ARGV;

Admittedly, the above is _somewhat_ atypical code.
