Interesting. I might have to rename some of my decorators to read well
that way, though. I'll play around with the idea a bit.
Of course, one of my use cases for class-level declarations is to work
around the fact that decorators can't be applied to arbitrary attributes of
a class, only to methods. Hm. Let me see:
foo = security.Anybody,
bar = myapp.User,
"""usage: some_command [-v|-q] [-f FILENAME] ..."""
verbose = [
options.Set('-v', '--verbose', value=True, help="Be loud"),
options.Set('-q', '--quiet', value=False, help="Be quiet")
filename = [
options.Set('-f', '--file', type=str, metavar="FILENAME")
Not bad. Not bad at all.
