A *with* statement in PHP?

with.php

<?php

/*
Ideally this would be part of the language:

    with (createAnObject() as $object) {
        $object->doStuff();
    }

This is just sugar for:

    $object = createAnObject();
    $object->enter();
    try {
        $object->doStuff();
    } finally {
        $object->leave();
    }

This isn't as necessary in PHP which has destructors. If you absolutely need
some clean up to run for an object, it can go in `__destruct`

interface ContextManager
{
    public function enter();

    public function leave();
}

final class ExampleContextManager implements ContextManager
{
    private $name;

    public function __construct($name)
    {
        $this->name = $name;
    }

    public function enter()
    {
        echo 'Entering Context', PHP_EOL;
    }

    public function leave()
    {
        echo 'Leaving Context', PHP_EOL;
    }

    public function getName()
    {
        return $this->name;
    }
}

function with(ContextManager $context, \Closure $callback)
{
    $context->enter();
    try {
        call_user_func($callback->bindTo($context));
    } finally {
        $context->leave();
    }
}

with(new ExampleContextManager('Test1'), function () {
    echo 'Indside Context: ', $this->getName(), PHP_EOL;
});

with(new ExampleContextManager('Test1'), function () {
    throw new \Exception(sprintf('Oops! %s', $this->getName()));
});
