Subject: Re: how about Array#collect_until

Here is an awful hacked solution...perhaps someone come up with a
prettier solution

class Array
  def try(something)
    contents = self.dup
    while contents.length != 0
      item = contents.shift
      result = yield(item)
      if something.call(result)
        p result
        break
      else
        p result
      end
    end
  end
end

%w[ find out if that  this  but not the other mother
mouth].try(Proc.new {|word| word[-2,2] == 'st' }){|item| item + "t" }

puts "another attempt"

[1,6,7,5,3,0,10,12,14].try(Proc.new {|num| num > 25 }){|item| item *
4 }

puts "another attempt"

[1,2,3].try(Proc.new {|x| x%2 == 0}) {|item| item + 10}

RESULTS:

"findt"
"outt"
"ift"
"thatt"
"thist"
another attempt
4
24
28
another attempt
11
12
