Problem/Motivation
Twig 3 is here
https://github.com/twigphp/Twig/releases/tag/v3.0.0
Proposed resolution
Update Drupal 10 to Twig 3.
Installing Drush on Drupal 10
Drush 10 has a dependency that requires Twig 1 or Twig 2 so is incompatible with Drupal 10. To install Drush at the current time do:
composer require drush/drush 11.x-dev
Remaining tasks
Discuss. Patch. Commit.
User interface changes
None.
