[erlang-questions] Pipe Operator in Erlang?

[Éric Pailleau]

Hi,
Yes, I forgot this. Joe's approach is more general. My wish is more prosaic, to let Erlang code syntax more compact and readable.
Erlang power is in asynchronous messaging, and ! is its operator. In the meantime some behaviours have synchronous call but need function calls, and no operator available. 
I suppose the reason is that not any Pid can answer back a synchronous answer. In such case an exception could be raised.
A = catch Pid |  {somemessage, somevalue }. 
This would probably need a timeout. On other hand,  ! + receive may wait forever. | could do the same.
