Yes.

However, the more Forth-style way IMO would be to notify the compiler
of the return-address manipulation rather than have the compiler
perform data-flow analysis.

In the usual (among return-address manipulating programs) cases it is,
but of course there could be things like:

( n ) begin
  dup while
    r> drop 1- repeat

But these cases are so rare that it would not be a problem to disable
inlining and tail-call optimization for all callers (even through
multiple levels of direct calls) of such words.

The main problem is EXECUTE etc. (e.g. DEFERred words); in most cases
you cannot exclude the possibility of an EXECUTE executing an
arbitrary word, including a word that performs some return address
manipulation.  So the compiler would have to disable inlining and
tail-call optimization for all words that contain EXECUTE or call
DEFERred words (and words that call such words etc.).  That would
disable these optimizations for a pretty large part of the code.

That's in the eye of the beholder.

What I find more problematic about return-address manipulation is that
it is not compatible with other (standard) features, in particular,
locals.  That's why it cannot be properly added as a feature to the
standard.

There is also the issue of processors that put the return addresses in
a place that is not accessible as data, but I doubt that Forth
implementations for these CPUs are fully compliant anyway, so if we
standardized return-address manipulation, that would be just one
standard feature among several that such a system does not implement.

Another implementation issue is that compilation-through-C becomes
harder and produces much slower code if it has to support
return-address manipulation.  However, AFAIK no such system is
currently maintained (not sure what became of Rob Chapman's Timbre
system), so maybe we should not worry about that too much.

The uses of return-address manipulation I have seen from Bernd can be
replaced without too much effort with quotations (nested variants of
:NONAME words) and words that take xts.  Some of the things Michael
Gassanenko has done may be harder to replace (not sure).

Overall, I think that we should add quotations and use them to replace
return-address manipulating code.  Then the compiler can happily
perform inlining and tail-call optimization.
