What about:

def source_text(arg)
  case arg
  when IO        then arg.read
  when Path.like then Path(arg).read
  else
    raise "Unable to find source text for `#{arg}`"
  end
end

or

def source_text(arg)
  case arg
  when IO         then arg.read
  when Path.like? then Path(arg).read
  else
    raise "Unable to find source text for `#{arg}`"
  end
end

The second is a bit too magic maybe.

The first seems more accurate IMHO
