Ways which could have been leveraged in PHP3. We don't use those ways because it's a PITA and produces unreadable code.

Here's three to get you started: Elixir: http://elixir-lang.org/getting-started/enumerables-and-streams.html#the-pipe-operator F#: https://msdn.microsoft.com/en-us/library/dd233229.aspx#Anchor_11 Clojure: https://clojuredocs.org/clojure.core/-%3E And if they seem to obscure, how about this proposal for Javascript? https://github.com/mindeavor/es-pipeline-operator >> Oh, sorry, we were talking about the function version of ->, my >> mistake.

The pipe call is clear and easily traces, the object call requires understanding OOP. I'll grant that OOP is much more common, and therefore generally understood by individuals who already know OOP (as tautologous as that statement is). -Sara -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
