Subject: Re: [PHP-DEV] Pipe Operator v2
From: david.proweb@gmail.com (David Rodrigues)

It's possible to use the tilde ~ easyly on keyboards?
For on BR/ABNT2 is easy. So maybe use ~> as operator could be fine,
instead of the triangle |>, and linear sounds good too, like:
$string~>escape($$)~>dump($$);

It's used currently on PHP for a bitwise operation (not), so I think
that the usage are not a problem in general.
Too will not have a conflict, because ~> no make any sense to PHP today.
