require 'socket'

socket = UDPSocket.open
socket.bind(Socket::IPADDR_ANY, 7090)

# what I have:
msg, host = socket.recvfrom(16)

# since host is an array, I can do this:
info, port, addr = host # last element is dropped

## Question #1:
# - Is there a way to make the assignments on lines 7 and 10 in one go?
#msg, [info, port, addr] = host # something along these lines?

## Question #2:
# - If I don't care about the addrinfo AF_INET thing, can I just not assign it?
# In Haskell you can use an underscore to capture from a list and discard
# values you don't need - is there a Ruby analogue for this?
x, y = %w{a b c} # c is dropped
#_, y, z = %w{a b c} # I want something like this where a is dropped


# IRB Session:
head :001 > _, y, z = %w{a b c}
 => ["a", "b", "c"] 
head :002 > _
 => ["a", "b", "c"] 
head :003 > y
 => "b" 
head :004 > z
 => "c" 
head :005 >
