Haven't seen Tango's arguments parser, but it's a given getopt can be

program, and things like checking against limits and constraints across
multiple arguments can be easily done after basic parsing.
The Python Standard Library's argparse module
<http://docs.python.org/2/library/argparse.html> would be a good model
to base an improved option parsing module on. I've used it a lot in
Python and it's very useful.

I remember sitting next to Kirk McDonald at the D conference in 2007 as
he was showing me Python's argparse. I personally found pretty much any
example we could think of more verbose and uglier than std.getopt.
