Yes, thank you for pointing that out. Forgot that there's a another thing named "tsx" out there.

I wouldn't call it running TS natively - what they're doing is either using an external tool, or just stripping types, so several things, like most notably enums, don't work by default.

I mean, that's more than enough for my use cases and I'm happy that the feature exists, but I don't think we'll ever see a native TypeScript engine. Would have been cool, though, considering JS engines define their own internal types anyway.
