I think this is a perfect example of where my desired "delayed" (or "deferred") construct would be great. There are lots of behaviors that I have not thought through, and do not specify here. But for example: def foo(a=17, b=42,, x=delayed randint(0,9), y=delayed randrange(1,100)): if something: # The simple case is realizing a direct delayed val = concretize x elif something_else: # This line creates a call graph, not a computation z = ((y + 3) * x)**10 # Still call graph land w = a / z # Only now do computation (and decide randoms) val = concretize w - b I do not find this particularly ugly, and I think the intent is pretty clear. I chose two relatively long words, but some sort of shorter punctuation would be possible, but less intuitive to my mind. -- The dead increasingly dominate and strangle both the living and the not-yet born.
