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.
std.getopt is definitely lacking some nice-to-have features (like automatically
generating --help from the options), but for the most part,
That's the part of argparse that I miss the most.
Also, its support for sub commands is excellent. I implemented a
version of quilt in Python and argparse made adding sub commands a
breeze once the main engine was complete.
I must admit that I toyed with the idea of implementing argparse in D
myself but rejected the idea when I realised that hard typing in D would
make it a non trivial exercise.
But I still think the basic ideas (i.e. integrated documentation,
specifying how many no option arguments there can be and support for sub
commands) are good. I especially like the integrated documentation as
it makes code maintenance much easier when everything about an
option/argument is in the one place.

PS before argparse I used to use getopt (C and Python) and I still
haven't decided whether I like D's version better than the originals
(probably yes for C and no for Python).
