Piper 19794ec27f Add UNFORGIVING mode 
* This will explicitly throw errors instead of handling them through
  Event Listeners
 2026-08-16 16:56:10 +02:00
Piper 8a95e0f98a Add ref binding 
* This will allow template-e6d users to also autobind references within
  their template for any more specific post-binding logic without
  risking ID conflicts.
 2026-08-16 16:52:11 +02:00
Piper 3b93bbc44e Add ability to set SELECT values 2026-08-16 16:28:27 +02:00
