[SciPy-Dev] usage of inspect.getargspec ?
Thu Jan 5 23:15:06 CST 2012
What is an isn't Pythonic seems to be a matter of some debate. I *really* like the idea of unifying those arguments. That simplifies the interface considerably.
I can understand the argument that it would be better to be explicit about it however. I see a couple of options:
1) add a property to the function to indicate what kind of function it is --- a simple 'kind' attribute on the function
2) wrap up the function as the callable of a Singleton Class --- one kind for each "type" of function call.
