At present, multi-argument function decorators are a little bit
tricky to implement.
As an example (somewhat contrived), suppose that `wait` is a function
decorator which haults program execution for a few seconds before
calling the wrapped function.
If you do not pass a float value into *delay* then the default value
is 1 second.
I would say this is a poor design. Just write "wait" so that you always
have to call it, and you just pass no arguments if you want the default.
So instead of this:
# default delay
@wait
def foo():
# custom delay
@wait(2)
def foo():
. . . you do this:
# default delay
@wait()
def foo():
# custom delay
@wait(2)
def foo():
