No, a recognizer can parse on its own (necessary for recognizing
"bla bla"), but the idea is to make the whole thing look like a word.
If we wanted to have a space in between, we could just as well just
have TO VALUE. I think that would be a conforming implementation of
the standard TO.
The reason why I think that we should avoid extra parsing if we can is
that, while Forth programmers sometimes like to think of parsing words
and what they parse as one unit (and try to accomodate that with,
e.g., STATE-smart words), sometimes they (either different programmers
or in a different context) expect the word to stand for itself, and it
would be surprising to them if it included the parsed stuff. E.g., if
somebody writes
... postpone to v ...
it might be surprising to the programmer or readers of the program if
this postpones "to v" rather than "to". If somebody writes
... postpone ->v ...
I think that everybody expects ->V to be a unit. For the
... postpone "bla bla" ...
case, it's pretty obvious that "bla bla" is a unit, so the
expectations of the programmers should not be a problem for that.
