Subject: Re: Read a file...

Arrange things that depend on the previous result to be in one bre block.

Does the rescue statement serve as a catch-all (for possible fuzzy thinking)?

Is normal|abnormal termination processing built into the language?

If all this is built into Ruby
  it's the greatest thing since sliced bread;
else
  it's (yet) another fad language.
end

So, -- for me -- Ruby is a whole new way of thinking.
I'll get it -- because it is fun to learn new things.
But it is a radical departure from what I've done for um, ..., over 3 days -- and I have the grey hare to prove it.

So there.
