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;

Posted in reply to Walter Bright | 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, bearophile |

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.
