## Description Ref #12556 To make things easier I've starting splitting up #12469 into smaller PRs. This first PR for codegen adds basic infrastructure for: * adding package imports * creating new var names (`*ast.Ident`) without conflicts Other PRs will add the actual codegen functionality. --- ### Author Checklist *All items are required.
