setTimeout does not work in REPL

[kevinkassimo]

In REPL, something like

> setTimeout(() => console.log(1), 1);

never fires

This is known/caused by the change from readline to being sync. @ry

Note: It would be good to test this once fixed.

Edit: I think a reasonable way to do that test is pass an optional kwarg to sleep between each input line.

Lines 15 to 16 in 34b6b86

	def input(self, *lines, **kwargs):
	exit_ = kwargs.pop("exit", True)
