  Hello internals,

  Following up on the keyword discussion: I ran an analysis tool
across 507,529 PHP files from the top +14,000 Composer packages.

  Results: https://github.com/azjezz/php-syntax-analyzer#results

  Summary: `let`, `using`, `scope`, and `block` have zero or minimal
conflicts (0-1 occurrences). `with` has 111 conflicts across multiple
packages and should be avoided if we decide to use a new keyword.

  Thanks,
  Seifeddine Gmati.
