This is going to cause problems with multiline, I suspect.

Concise example:

const regexps = new Set<
  RegExp
>();

If typed as multiline input to REPL, it's going to consider the statement complete after the second newline, as it's a valid JS statement, and evaluate new Set < RegExp, which evaluates to true. I don't know that there's any way around these sorts of parsing conflicts.

It should be handled exactly like we handle the -e and -p. If it's valid js treat it as such otherwise fallback on TS
