Subject: Re: [PHP-DEV] [RFC] Short syntax for anonymous functions

As I stated before suggesting the syntax: It's only meant for a single
expression. It's purposefully NOT intended to cover multiple
expressions.  In that case the current (verbose) syntax is better for
all criteria I care about. Additionally, neither Python nor Dart
allows multiple expressions in their short-syntax functions.
