Howdy all,
I want an explicit replacement for a common decorator idiom.
There is a clever one-line decorator that has been copy-pasted without
explanation in many code bases for many years::
decorator_with_args = lambda decorator: lambda *args, **kwargs: lambda
func: decorator(func, *args, **kwargs)
My problem with this is precisely that it is clever: it explains nothing
about what it does, has many moving parts that are not named, it is
non-obvious and lacks expressiveness.
Even the widely-cited ActiveState recipe by Peter Hunt from 2005
<URL:http://code.activestate.com/recipes/465427-simple-decorator-with-arguments/>
gives no clue as to what this is doing internally nor what the names of
its parts should be.
I would like to see a more Pythonic, more explicit and expressive
replacement with its component parts easily understood.
