# Unit is a special object you can use whenever your computations don't
# return any payload. Previously, if your function ran a side-effect
# and returned no meaningful value, you had to return things like
# Success(nil), Success([]), Success({}), Maybe(""), Success(true) and
# so forth.
#
# You should use Unit if you wish to return an empty monad.
#
# @example with Result
# Success(Unit)
# Failure(Unit)
#
# @example with Maybe
# Maybe(Unit)
# => Some(Unit)
#
Unit = Object.new.tap do |unit|
