Because we have redefined the left parenthesis, from this point on, inline comments must be done with a double left parenthesis.

## Defining KISS-commands
      KISS +      KISS -       KISS *       KISS /
Indeed, that's all there is to it to make KISS-commands out of existing Forth words! From this point on, `+ - *` and `/` act (almost) like they do in, e.g., BASIC. Or to put a finer point on it: A KISS-command uses the immediately following word as its argument: infix-notation, ex. 1. When a left parenthesis is found, all words up to the right parenthesis are arguments: prefix-notation, ex. 2. Take care: Parentheses are Forth words and must be separated by at least one space from the preceding or following text. Precendence rules are not implemented (check out ex. 3, 4 and 5).
    1)  BASE @ + 1 .         \ 11
    2)  1 + ( BASE @ ) .     \ 11
    3)  3 + 4 * 5 .          \ 35
    4)  ( 3 + 4 ) * 5 .      \ 35
    5)  3 + ( 4 * 5 ) .      \ 23
KISS-commands work inside definitions.
