The following program fails to compile for me (DMD 2.052, OS X):

import std.typecons, std.container;
void main() {
    alias Tuple!(real,string) Entry;
    Array!Entry Q;
}

The error is:

phobos/std/container.d(1549): Error: this for _data needs to be type Array not
type Payload
phobos/std/container.d(1550): Error: this for _data needs to be type Array not
type Payload
phobos/std/container.d(1551): Error: this for _data needs to be type Array not
type Payload

If "string" is replaced by, say, "int", it works.

The problem here is Array cannot have slice members. Reduced test case:


import std.container;
void main() {
    alias Array!(int[]) A;
}

The 3 lines in reserve() that emit the errors


                GC.removeRange(_data._payload.ptr);
                free(_data._payload.ptr);
                _data._payload = newPayload;


should probably read


                GC.removeRange(_payload.ptr);
                free(_payload.ptr);
                _payload = newPayload;
