Looks like tsconfig "module: esnext" is the culprit.

Ok

I assume this has been resolved. If not, feel free to reply and we can re-open.

So this happens with "module": "NodeNext" as well, although I don't understand why this happens with either option.

Like shouldn't the repl mode always compile the code given as CommonJS/script regardless of the "module" field?

Yeah, I think the bug here is that we don't force the repl to be CJS even in ESM projects. I thought I already had a ticket for this; can you check for one and, if not found, file a new bug report?

I think this is #1752

Thanks, I added a comment on that issue about a couple possible ways to fix it.
