Composing generic abstractions, including dropwhile:
<lang python>from itertools import (chain, dropwhile)
def main():
print(▼
nuggets = set(
concatMap(
lambda x:
concatMap(
lambda
concatMap(
lambda
)(fromTo(100 //
)(fromTo(100 //

xs = list(dropwhile(
▲ enumFromTo(0)(100 // 6)
lambda x: x in
enumFromThenTo(100)(99)
)
▲ print(
xs[0] if xs else 'No unreachable quantities found in this range.'
)
