I think that warning is only given if the value being assigned is a
literal:


   if a = 1
     puts 99
   end
 =>
   -:3: warning: found = in conditional, should be ==
   99

But...

  def dave
    1
  end

  if a = dave
    puts 99
  end
 =>
  99


That means that common idioms (idia?) such as

   while line = gets

Compile without warning.
