What about using Object#try and avoiding the explicit &block argument?This
avoid to instantiate a Proc object *for each* method execution, if any block
isn't passed and the enumerable is empty the VM will raise a LocalJumpError.
module Enumerable
def else
self.try(:empty?) ? yield : self
end
end
Please look at this benchmark (http://gist.github.com/163274) my
implementation is exactly 4x faster ;)
Cheers,
Luca
