Destructuring Ruby hashes with named parameters and anonymous splat

anonsplat.rb

def stuff
  yield action: 'Boom', schedule: '7PM', color: :red, debug: true
end

# When a hash is yielded to a block, we can used named arguments to
# capture the keys we want, and an anonymous splat to ignore
# everything else
stuff { |action:, schedule:, **| p "Doing #{action} at #{schedule}" }

#
# > ruby ./anonsplat.rb
# Doing Boom at 7PM
