OK, more smart optimising .

I can't see how to do eg:
  foobar[1] ->   foobar[2]

IMO, inductive (by examples) is not a substitute for a proper syntax
definition eg. of the 'native' words.

I belong to those just wishing to find a better than assembly way of 
programing pics, and am not prepared to allocate much resources to
researching linux nor forth.

It may be usefull to now know what '2>'  means, but if potential
picforth users have to make such research, they will just rather abort.

 What is the current situation - will the 'table facility' be available ?
