Problem & expected behavior (under 200 words)

tsx accepts Typescript single line inputs, but not multiline inputs, unlike ts-node.

ts-node:

username@localhost:~ $ ts-node
> function stringify(num: number): string { return "" + num; }
undefined
> function unstringify(num: string): number {
... return +num;
... }
undefined
>

tsx:

username@localhost:~ $ tsx
Welcome to Node.js v21.7.1.
Type ".help" for more information.
> function stringify(num: number): string { return "" + num; }
undefined
> function unstringify(num: string): number {
function unstringify(num: string): number {
                        ^

Uncaught SyntaxError: Unexpected token ':'

This issue is not reproducible with the StackBlitz template provided, since it involves interactive use of the CLI rather than running a file.
