Here are three things I'd like to see in any new auto-capturing closures RFC:


1. JUSTIFICATION

Don't assume that everyone already thinks it's necessary and desirable.
Try to come up with some real-life examples where you would want to use it.
Acknowledge the possible down-sides, and explain why you think they're
justified.

<?php

class Transaction implements ContextManager
{
  public function __construct(private Database $db) {}
  
  public function contextEnter() {
    $this->db->beginTransaction();
    // Could return some other representation of the transaction if appropriate
    return $this;

            $args = wp_parse_args( $args, array(
                'response_type' => ARRAY_A,
            ) );
