FR: Either multiline support or stop-paste-on-error #1352
Description
Desired Behavior
Copy-paste below code into ts-node twice, and only get Duplicate function implementation error.
function add(x: number, y: number): number {
return x + y
}Current behavior
$ ts-node
> function add(x: number, y: number): number {
... return x + y
... }
'use strict'
> function add(x: number, y: number): number {
[eval].ts:1:10 - error TS2393: Duplicate function implementation.
1 function add(x: number, y: number): number {
~~~
[eval].ts:4:10 - error TS2393: Duplicate function implementation.
4 function add(x: number, y: number): number {
~~~
[eval].ts:4:37 - error TS2355: A function whose declared type is neither 'void' nor 'any' must return a value.

The parser expected to find a '}' to match the '{' token here.

Is this request related to a problem?
Frustrated when I paste in a function I've defined before and get a pile of errors.
Alternatives you've considered
You can put the code in a block to redefine functions, but maybe I'd rather get the error.
ts-node
> function add(x: number, y: number): number {
... return x + y;
... }
'use strict'
> add(5,10)
15
> {
... function add(x: number, y: number): number {
..... return x + x + y + y;
..... }
... }
[Function: add]
>
undefined
> add(5,10)
30

Additional context
I heard there is better multiline support coming to node repl sometime and it might automatically solve this. I don't know much about REPLs or if you have a reliable way to detect if code is being pasted instead of typed.
