Yes. A good example of this is that earlier standards prescribed 
implementation details, such as cell size and threading method. Neither 
16-bit cells nor indirect-threaded code is wrong in itself, but should 
not be constraints on the implementer.

There is no official "reference implementation" of any of the standards. 
'F83' attempted to be one for Forth83, but had a couple of 
incompatibilities.

Several systems in wide use are tracking this standard, but all contain 
additional features that are not appropriate for a true "reference 
implementation".

I agree.

I really agree with Stephen here. You will find your project much easier 
if you have a working, well-documented system and learn to write at 
least some Forth code. No standard is intended to be a tutorial. You 
will not gain much of a real "understanding of Forth" by just building a 
system to spec. Building a bicycle doesn't teach you to ride one.

There are good modern systems, both open source/public domain (gForth, 
Win32Forth) and free evaluation versions of commercial systems from MPE 
and FORTH, Inc. The latter have extensive documentation and lots of code 
examples.  SwiftForth, from FORTH, Inc., includes the Forth Programmer's 
Handbook as well as its own manual. There is also a tutorial I wrote, 
Forth Application Techniques, available at low cost from Amazon.

Cheers,
Elizabeth
