This should be public_send, for maximum clarity.

I don't think ||= will be a good enough check. Different args or a block should produce different results.

This line can be deleted. All ruby ...=... syntax always returns the right most expression.

IMO respond_to?(:map) is too weak of a trait check. Any object could have the method map and not be a collection.

@krainboltgreene thank you for your review. I'll address your proposals. |

@wuarmin FWIW I don't envy your task! Cache-level optimizations are hard and can be unpredictable at the library level. |

Hello ;)
What is your opinion on my proposal?
It solves huge performance issues for us, because we are dealing with objects with slow and unchangeable getter-methods.
We had a conversation at #99.
Thank you for your feedback.
