Feature #8896
open#tap with missing block
Description
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.

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.

#tap without a block returning self makes sense

If the LocalJumpError
breaking change from this ticket is not an issue then it'd be pretty easy to add logic to that PR^ supporting it.
