I showed a fellow programmer std.getopt. We were both on

argparse was much more verbose and less pleasant to use than
getopt. Like you have to create an object (?!?!) to parse the
command line and many other lines of nonsense.
I've found D's getopt package to be pretty good. There are a
number of small things that could make it quite a bit better. To
me these generally appear more the result of limited usage rather
than anything fundamentally wrong with the design.
For example, error text produced when a run-time argument doesn't
match the option spec is often not helpful to the user who
entered the command, and I've found I need to take steps to
address this. A package like Perl's Getopt::Long tends to a bit
more mature in some of these details.
