Let's continue.
      KISS .      KISS EMIT
      . 3                  \ 3
      . ( 3 + 4 * 5 )      \ 35
Nesting is allowed (12 levels deep):
      . ( 3 + ( 4 * 5 ) )
      . ( ( 3 + 4 ) * 5 )
Mixing with other Forth commands is no problem:
      . BASE              \ 291976 (at least one Forth)
      . ( BASE @ )        \ 10 (parentheses needed!)

      . ( BASE @ 1+ )     \ 11
      BASE . ( @ 1+ )     \ 11
      BASE @ . 1+         \ 11

      . ( BASE @ + 5 )    \ 15
      BASE . ( @ + 6 )    \ 16
      BASE @ . ( + 7 )    \ 17
Undoubtedly many more variants are possible.
      . ( 9 + DUP )       \ 18
      . ( 1 20 - SWAP )   \ 19
Incredibly flexible, no doubt, but easier? Let's explore even further.
      KISS >      KISS <     KISS =      KISS <>
      KISS IF     KISS THEN
      KISS AND
      : TEST (( x -- )
        CR . DUP ." is "
        IF ( DUP = 0 )  THEN ( ." zero " )
        IF ( DUP < 0 )  THEN ( ." negative " )
        IF ( 0 < over ) THEN ( ." positive " )
        ." and "
        IF   ( = ( 1 AND TUCK ) )
        THEN ( ." odd." ELSE ." even." ) ;

      KISS TEST

      TEST ( 100 - 111 )     \ -11 is negative and odd.
