Let me ask a related question:  is there a accepted standard
of where the |...| go?

This is what I have been doing:

One-liners look like:

    [1, 2, 3].each { |x| p x }

Multi-liners can look like:

    [1, 2, 3].each { |x|
        p x
        p x + 1
    }

or

    [1, 2, 3].each {
        |x|
        p x
        p x + 1
    }

or

    [1, 2, 3].each do
        |x|
        p x
        p x + 1
    end

I don't often use "do |x|\n" ... not sure why.

I'm trying to decide which of the 3 multi-line versions to commit
to using, but it seems there's no One True Way from the sample
code I've been reading over ...
