The |> symbol would be the piping operator with these semantics: 
     1. Evaluate the left-hand side.
     2. Evaluate the right-hand side. Assert that the result is callable.
     3. Pass the result from 1. as the single argument to 2.
May I suggest extending your 3rd rule to : when the right hand side has the form of a function call, insert the result from 1. as first argument of 2. This way, right hand side may specify additional arguments. Based on the fact that, in 99% of PHP builtin functions where the concept applies, the 'input' argument is the first one. Example : $string |> trim('.,;:') $string |> trim() IMO, not acceptable : $string |> trim Regards François
