Subject: Re: [PHP-DEV] [RFC] Function pipe operator
From: mike@newclarity.net (Mike Schinkel)

A questions and a comment:

1. How will XDEBUG handle a multiline construct such as this?  Will it =
treat as one expression, or allow breakpoints at each "link" in the pipe =
chain?

Maybe this is a better question for Derek Rethans?

2. The exclusive use of callable seems problematic prior to an inclusion =
a '::function' operator that can be applied to functions for symbol =
resolution to function name as it will encourage more use of strings =
that are not checked by PHP.  Maybe we could address that first?

Also #2 would be true for method names although how that might be =
implemented is a bit more complicated.
