Oh, that's clever, and I might even have thought of that myself if it
wasn't described as "off-topic" *wry smile*
So in a generator comprehension, what would it do?
(*chunk for chunk in values)
# equivalent to... ?
# (item for chunk in values for item in chunk) perhaps?
I guess we could allow an equivalent in dict comprehensions:
{**chunk for chunk in values}
for unpacking nested dicts or (key,value) pairs.
Clever... or maybe *too* clever?
