Hello Walter,
How do we fix the CPU? ;-)
I was thinking 220VAC might help!
That one way to be totally sure what is wrong with your CPU.

Sounds great :)
But I think there's a minor typo here:

There's a large number of changes!
I don't understand what No more comma operators allowed between [ ]. means.
I have tried the D2 compiler a little with this code:
import std.stdio: writeln;
import std.math: pow;
struct S1 { int x; }
void main() {
struct S2 { int x; }
static struct S3

But what do I have to import from math to use 5.2 ^^ 2 ?
Anyway, the need to explicitly import something to use a built-in operator like

A very bad idea indeed! The idea is to save

Can't import std.math : pow; be added to the current module when this
is needed?
Note that this code doesn't compile:
import std.stdio: writeln;
import std.math: pow;
void main() {
writeln(5.2 ^^ 2);
}
This is what the compiler shows:

It's desperately important that the language spec becomes stable before

Yeah, that was a pretty evil bug. It has been lurking there for probably
18+ years now. It's evil because only a very, very rare set of
circumstances will trip it, and even then it may not be executed or noticed.
