RfDs welcome. Note that some ideas for removing ambiguity that some
people have advocated (in particular, requiring a separate
control-flow stack) are contrary to common practice and are therefore
unlikely to be accepted.
And somehow it seems to be much harder to remove explicit ambiguity
than to add new words, even if deciding for one way on this ambiguity
is much more common practice than the new words.
As an example, we decided to standardize a separate FP stack back in
2008, yet in the last two meetings a committee member brings up again
and again that on some particular CPU one can gain some efficiency
(without providing numbers) by having a system with (now) an
environmental restriction of having a shared stack with single-cell FP
values, *and* writing a program that even in Forth-94 has an
environmental dependency on a shared stack with single-cell FP values.
Interestingly, when I compare programs without environmental
dependencies, I expect that a Forth-2012 program (that relies on the
separate FP stack) will be similarly fast on that particular CPU (and
easier to write) compared to a Forth-94 program, while the Forth-2012
program runs faster on most other CPUs, and I have numbers for that:
With gforth-fast on a Core i7-4790K (4.4GHz):
Forth-2012 Forth-94
500x500 mm - normal algorithm 0.570s 0.727s
500x500 mm - transposed B matrix 0.550s 0.686s
500x500 mm - Robert's algorithm 0.547s 0.684s
