[Speculating] Could we use metaclass thingies to defer the call to __init__ or wrap somewhat the future arguments?

from simpleflow.

I don't know "metaclass thingies" (yet), pointer?

from simpleflow.

Sorry, no pointer found... __metaclass__, __new__, __call__ or some such things, but it's hand waving...

from simpleflow.

Oh ok, I thought there was something special in abc or equivalent to do lazy evaluation or some other black magic. I'll read the docs about metaclasses then!

from simpleflow.

No magic, just metaprogramming :-)

It's easy, really. Just parse __init__'s arguments. If any is a Future, replace it with its result getter 😉

(I discovered a really marvelous implementation that this comment box's margin is too small to contain)

@ybastide gist it ? :)

Thanks Mr Fermat ;-) Actually I may find a smart solution with __new__, didn't know you have access to that in python!

Arg, last problem (but not least): examples work well with ONE instance of a given task, but they'll mix up in the registry if there are two of them. We need to refine their name to include a unique ID per object. Going down the rabbit hole :(
