Complex commands with Rulang

Rulang was giving me a lot of trouble with regards to multi-line commands and complex commands in general. After hacking on it for a while I've developed a patch that will allow ruby code such as the following: 

require 'rulang'

@mnesia = RulangBridge::Erlang.new("localhost", 9900)

def find
  @mnesia.eval(<<-EOF
    QH = qlc:q([X || X <- mnesia:table(shop)]),
    F = fun() -> qlc:eval(QH) end,
    {atomic, Val} = mnesia:transaction(F),
    Val.
  EOF
  )
end

puts find
