True, but tweakdoc doesn't have to be a function, so IMO we need a better
name for the @-line, unless you want to use many various specific names
like factory. E.g.,
(Preliminary definition):
>>> class Deco(object):
... class __metaclass__(type):
... def __getattribute__(cls, name):
... if hasattr(type(cls), name): return type.__getattribute__(cls,
name)
... def decorator(f):
... f.func_name = '%s_%s'%(f.func_name, name)
... return f
... return decorator
...
>>> deco = Deco
Ok, now what do you call this @-line? Freaky decorator factory invocation?
Decoratoriferous expression? ;-) Lexical decoration?
Decorator{-producing,-generating, ??} expression ?
Decorator expression for short? vs the decorator callable produced.
>>> @deco.one
... def foo(): pass
...
>>> foo
<function foo_one at 0x02EE8E2C>
>>> @deco.three
... @deco.two
... def bar():pass
...
>>> bar
<function bar_two_three at 0x02EE8E9C>
