I've successfully compiled Tango with dmd1beta.

But one of my apps don't compile anymore.
Is it a bug?:

uint* getInstance() {
    return new uint;
}

struct Foo {
    uint* x;
}

void main(char[][] args){
    Foo o = {getInstance()};
}
/*
main.d(226): Error: Cannot interpret new uint at compile time
main.d(236): Error: cannot evaluate getInstance() at compile time
*/

That looks like a bug in your code.  If it was allowed before, I wonder what was put into the o instance.

anything between {} has to be evaluated at compile time, I think that rule has been in force for a long time.

The code should be:

Foo o = Foo(getInstance());

No it didn't have to be evaluatable at compile time. In response to http://d.puremagic.com/issues/show_bug.cgi?id=2380 Walter added this to the spec:

-
The static initializer syntax can also be used to initialize non-static
variables, provided that the member names are not given. The initializer need
not be evaluatable at compile time.
-

So this sounds like a regression.
