How can I handle the char immediately after its input, without waiting an endline?

I can't think of any modern apps that use one character commands like
that. One character plus a modifier (ctrl or alt generally) perhaps, but
even there, it's mostly used in GUI applications.

Absolutely not! There's no need for it to be given a keyword or special
But maybe there should be a standard library function for it.

No. Leave raw_input as it is. A better interface would be:
c = input_services.get_char()
Eventually the module could grow other services as well.
