I usually go the way of a hash/hashref for complex constructors, as I
feel this offers a more intuitive model rather than an order list of
values. I mentioned hash/hashref as I often do something like this ...
sub foo {
my %options;
if (ref $_[0] eq 'HASH') {
%options = shift;
} else {
if (scalar(@_) % 2) {
%options = @_;
} else {
croak( 'Uneven number of arguments passed to foo - Argument
should be a hash or hash reference' );
}
}
}
