Subject: Re: how exit a block?

Have you tried using detect?

colors = ['red', 'yellow', 'green', 'blue']
yellow = colors.detect { |color| color == 'yellow' }

Detect runs the block on each element until the first that returns true.

>> colors = ['red', 'yellow', 'green', 'blue']
=> ["red", "yellow", "green", "blue"]
>> yellow = colors.detect { |color| color == 'yellow' }
=> "yellow"
