I think that I didn't opposed myself to the pattern:
sub xpto {
my $var1 = shift;
my $var2 = shift;
...
}
Where it is clear that you wont to assign the parameters. 90% of the
times I prefer to have pattern
sub xpto {
my ($var1, $var2) = @_;
...
}
since, in my opinion, makes the intentions more clear.
Now setting shift inside logic, I clearly say: please add the @_ and
make clear that you know the array that you are using, make clear your
intentions.
Best regards
