Bug description:Static lambdas not documented
Description:
------------
Neither http://php.net/manual/en/class.closure.php nor
http://www.php.net/manual/en/functions.anonymous.php
mention that anonymous
functions / lambdas bind the object they are defined in to $this, and that
the
automatic binding functionality can be avoided by declaring the lambda as
static:
<?php
$lambda = static function() { ... }
?>
There should probably be a warning about generating lambdas in object
contexts
as it silently binds a reference to the defining object, which could cause
all
sorts headaches when attempting to cause the destruction of an object.
Defining a static lambda like the code sample above prevents the lambda
from
binding to its defining object. Please patch the documentation
accordingly.
Thanks!
