Description
Describe the bug
TypeScript 5.2 supports an upcoming ES feature, using: https://devblogs.microsoft.com/typescript/announcing-typescript-5-2/
The syntax doesn't get transpiled by vitest, and then tests fail with the following error:
Error: Parse failure: Unexpected token (6:10)
At file: /home/projects/vitest-dev-vitest-uk35mv/test/basic.test.ts
Contents of line 6: using disposable = {
When I run the files that use the using syntax with https://github.com/esbuild-kit/tsx, it works just fine.
