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 lives and control the thoughts of homo faber. Ideas, once born,
become abortifacients against new conceptions.
