Are you sure ? You said the same exactly 1 week ago.

* What about DEC Ada ? It has very smart and aggressive optimisations
that make use of Ada features - subtyping, strong typing, precise
definition of arrays, and so on.

* What about GNAT ? The code generator has been used for successful
video games (Quake not to name it...). With the suppress_all (-gnatp),
cross-unit inlining (-gnatn), -O2 options, it rocks! And
GNAT 3.13p should have Ada-specific optimisations around array
indexing, aggregates, slices. Prior to that, I invite you
to test my small full-Ada 3D engine, compiled with 3.10p. Link below.
300 frames per second on a 450Mhz machine (~25 needed for smooth animation)!

I don't think, too.

It's not reasonable. Pure waste of time:

1) C++ is already complicated enough. Who really understand or uses its
features, at which extent ? IT people are conservative - for
good reasons. Wait first they use "C++" rather than "C*1.001"...

2) C/C++ is indeed itself a small niche in the *whole* IT world. Think
to business, finance, banking, insurances and so on.
With normal people who have calculations to do with some data.
What do they use ? Maybe still COBOL. But more and more: Visual Basic for
Applications. With procedures, functions, if..then..elsif..endif structured
blocks, strings concatenated with '&', exception parts.
Hey, what does it look like ?... So, what can be the "natural" ISO language
for doing things in a larger scale ? Long life to JEWL, CLAW, VAD,... !
