It all depends on what the function is doing. For complex data
structures, references are definitely the way to go. For large numbers of
scalar values, I like to do this:
my_func(arg1 => 'value1', arg2 => 'value2', ...);
and in your function:
sub my_func {
my %params = @_;
$params{arg1}++;
...
}
You can also set defaults in your function and override them if necessary:
sub my_func {
my %params = (
arg1 =>'default1',
arg2 => 'default2',
@_
);
...
}
