Just a thought from an iffer (cases are ugly in Java, so I just got
used to always iffing):

case i
  when arg,a
    ...
  when arb,b
    ...
end

isn't much different from

if [arg,a].include?( i )
  ...
elsif [arb,b].include?( i )
  ...
end

include? is possibly less efficient, though. Haven't benched it.
