Your trick forces the use of Yoda conditions, which may be tricky and cryptic.

Hi,

I was thinking I often do things like `collection.detect { |item| item.attribute == value }` and a shorthand like `collection.detect(:attribute, value)` would be quite useful

What do you think?

And I know there is `collection.detect { _1.attribute == value }` but I try not to use `_1` and this syntax would be shorter and simpler

Could also apply to other methods like `all?` (`collection.all?(:attribute, value)`), and basically any Enumerable method https://rubydoc.info/stdlib/core/Enumerable
