I found that sometimes I want to return a simple value without wrapping it in a proc. This pull request adds support for non-callable defaults when no items match. (({a = [1, 2, 3]})) The current behavior (({a.find(proc { :foo }) { |x| x > 3 } #=> :foo})) With patch (({a.find(0) { |x| x > 3 } #=> 0})) =end -- http://bugs.ruby-lang.org/
