In any case, naturally, I didn't intend that you actually name the arguments
as "$arg1" , "$arg2" , "$arg3" , etc. literally. This was just done for
clarity.
An actual use case may be:
[code]
sub send_message_to_user
{
my $self = shift;
my $user = shift;
my ($format, $format_params) = @_;
# Do some sanity checks
if (ref($format) ne "")
{
confess "Format is not a string!";
}
if (ref($format_params) ne "ARRAY")
{
confess "Format parameters should be an array reference.";
}
return $self->_get_user($user)->send_message(@_);
}
[/code]
A little contrieved, but I've done it before.
Naturally, naming your variables as $name1, $name2, $name3 is indicative that
you need a hash or an array. See varvarname:
