> pipeline operator

no thanks, I don't think it's an interesting feature, there are alternatives (chaining, promises, ..) to avoid the cost of this new syntax

Other proposals I'm more excited about:

- https://github.com/tc39/proposal-iterator-helpers

- https://github.com/tc39/proposal-slice-notation/ (and https://github.com/tc39/proposal-slice-notation/pull/32)
