# A multiple assignment written inside a group answers its right-hand side.
p((a, b = 1, 2))
p [a, b]

p((first, second, third = 1))
p [first, second, third]

# `defined?` reports on an assignment without carrying it out.
p defined?(counted = 1)
p defined?(@held = 2)
p defined?($named = 3)
p defined?(counted %= 2)
held = []
p defined?(held[0] = 1)
p held
