You're probably right, because someone already _has_ come up with that:
https://github.com/carymrobbins/python-blocks/blob/f51d10bd2439990cce7e2cb78e6e56ed05e78648/src/blocks.py#L191
Anyway Chris, to answer your question, the python-blocks repo shows the
'functional decorator style' taken to its logical conclusion, with
decorators for all the various functional building blocks like mapping,
folding, currying, etc.
Incidentally, with a properly-defined decorator 'factory', you could get
a pretty generic decorator for your dispatch example:
cmd = {}
dispatch = make_dispatch(cmd)
@dispatch
def foo(*args): print("You asked to foo.")
@dispatch
def bar(*args): print("There's no wine in the bar.")
@dispatch
def cmd2(*args): print("Asdf! Asdf!")
cmd["foo"]()
# Etc.

Yawar
