What do you mean non-standard?  They're standard.  ANSI C standard ...

Since you apparently think Forth has an insufficient quantity of operators,
I don't see how you're ever going to solve the problem of introducing "some
more non-standard operators".  You don't write the Forth specifications.

No, it wouldn't have been hard.  Apparently, that's not an issue for Forth
since it's simple to do and yet not present.

You mean NOT, ANY, and BOTH are logical operators?  How do you intend to
check that the values to ANY and BOTH are booleans?  If you don't plan on
checking, then how are ANY and BOTH different from OR and AND respectively?

One of the reasons I like C is because the syntax for names of objects and
language elements are alphabetic, numeric, or both while the syntax for
operators are purely symbolic.  It keeps the language easy to read ...

Converting part of those to C syntax (unchecked as to correctness):

         r@ 3 /mod swap ! && &&
         r@ 3 /mod 0 != swap 0 = & &

! is logical not, && is logical and, != is logical not equal, & is binary
and, etc.

C doesn't have an exact equivalent to /mod, it has / for division and % for
remainder:

  2DUP / -ROT %

But, in Forth, / could be redefined to compute both quotient and remainder
like /MOD.  However, it would only place the quotient on the stack and store
the remainder.  Then, % could retrieve the remainder when needed, reducing
that to:

  / %

So, we could end up with something like this:

         r@ 3 / % swap ! && &&
         r@ 3 / % 0 != swap 0 = & &
