And other things wouldn't work. That's not an increase, it's a shift.

It is.

Sure it does. Bernd Paysan presented one example:
: myconstant ( n "name" -- )
>r : r> postpone literal postpone ; ;
5 myconstant foo
foo .
If : invoked the text interpreter, as you desire, this would result in
a "undefined" word error at the second occurence of FOO instead of the
intended behaviour of definining a colon definition equivalent to
: foo 5 ;
and then executing it and printing the result.

It's non-standard. Why is it non-standard? There may be something in
the standard that discusses the reasons, but I do not find it at the
moment. Anyway, the standardized approach certainly had been widely
practiced in systems such as fig-Forth, and apparently the committee
felt that the benefits to programs of standardizing it outweighed the
benefits to systems on not standardizing it. As someone who makes use
of this feature in my programs, I think that was the right decision.
