Thanks. That's actually the first time I've written code that yields. =
It's actually bit unclear to me as to when it's better to return results =
and when it's better to yield them. I guess the best thing to do would =
be to check, what is it, block_given? and either yield or collect the =
results as appropriate. Do more advanced rubyists have any guidance to =
offer in this regard?
