Can someone explain this "new feature" please ?!

"Added support for op= for array.length"

array.length = X; cannot be meant...

I just noticed: I don't see @property in the changelog anywhere, but it's now in the spec. @safe, @trusted, @system aren't there either.

  int [] x = new int[30];
  x.length += 5;

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 { int x; }
    writeln(S1.sizeof, " ", S2.sizeof, " ", S3.sizeof); // 4 4 4

    auto a = [1, 2, 3];
    writeln(a); // 1 2 3
    a.length++;

    //writeln(5 ^^ 2);
    writeln(5.2 ^^ 2); // errors
}

S2 seems to not have the hidden field, The sizeof is the same for all three structs.

a.length++ seems to not work yet.

writeln(a); prints stupidly items separated by a space. A MUCH better print is:
[1, 2, 3]

5 ^^ 2 doesn't work yet, I guess it's not implemented yet.
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 ^^ looks like a bad idea.

Bye and thank you,

I assume that means:

int[1,2,3] foo; // <- formerly created an int[3], now (presumably) disallowed

Yes, you are right, that's probably it, thank you.

Was this feature documented anywhere?

I don't think it was ever really a feature, it was just a consequence of the next-to-useless expression "x,y" evaluating to "y" and "int[...] foo;" taking a single value for "...".

A very bad idea indeed! The idea is to save keystrokes...

Can't "import std.math : pow;" be added to the current module when this is needed?

Great! Can you tag the new releases? (and maybe the old ones too ;)

This should be enough:
svn cp http://svn.dsource.org/projects/dmd/branches/dmd-1.x http://svn.dsource.org/projects/dmd/tags/dmd-1.053
svn cp http://svn.dsource.org/projects/dmd/trunk http://svn.dsource.org/projects/dmd/tags/dmd-2.037

The same should be done in the phobos and druntime repositories.

Thanks!
