The idea here is to allow a bit finer grained control over the
Input
function without disturbing the current API. When usinggo-prompt
in a custom REPL it's useful to know when something likeCTRL+D
was pressed so that the loop can terminate, since there's no way to distinguish between empty input""
and an exit request. For your consideration.
