Right.  I've made it kind of work in Mailman 3, but it would be nice  
for argparse to support this out of the box.  Note that I think you  
want two forms:

foo help subcommand
foo subcommand --help

to basically print the same help text.  This is the way bzr does it  
for example and it works great.

Other than that, I think argparse supports Guido's use case very nicely.
