Hello,
I usually use my ($arg1, $arg2) = [at] _;
to get the arguments parsed to a subroutine.

I want this to be smarter. Sometimes I want to pass $start, $end to
the sub, sometimes I want to pass $start, $count to the sub.

but in this case my ($arg1, $arg2) = [at] _; will get confused, it
doesn't know if the argument is meant to be $end or to be $count.

does subroutine have some mechanism like getopt::long and it can know
what kind of arguments are passed in?

Thank you in advance for pointers,
Jim

Jim,

You could pass a hash reference instead.

%arg = (start=>'..',end=>'..',count=>'..');
the_func(\%arg);
