Hi Christopher,

Philosophically, that's just the kind of thing I wanted (dynamic
application of criteria) but didn't have the wit to describe it.

As you saw in my post, I had the statement:
puts greek.all? { |s| s.length == 5 }

But if I had a number of criteria and values to apply, my code would
get messy fast and invite copy & paste errors.  Your code is tidy,
more readable and can be made as short as I wish without loss of
clarity.

Many thanks,
Richard
