It seems pretty specific to the Rails domain of homogeneous arrays of model objects, readable-as-English code, and the need for blazing-fast development. With those as givens, of course, this is pretty neat. @Dr Nic [via] - Yeah, ok, but only in Rails does this make a difference.

I only had some trouble with the regex for the 'respond_to?' method. The regex in map_by_method_regex is: /(map|collect|select|each|reject)(_by)?_([\w\_]+\??)/ which does (unfortunately) also match 'each_pair'. This caused some trouble in my app since an array responds to a method that belong to hashes. Removing the '?' after '(_by)' in the regex works for me. @Dr Nic [via]
