> I would like to see tap return an Enumerator if a block is not passed.
Can you explain your suggestion a bit more? I can't imagine realization and use-case yet.

Feature #8896: #tap with missing block

In case when no block provided to tap, it fails. So if you want method which can be called with or without block - you can't do it like this:

def self.create(args={}, &block)
  new.set_attributes(args).tap(&block)
end

but should use block_defined? to prevent #tap's failure.

I suggest to make tap with no block given just to return self and raise no errors.
