This compiles in DMD 2.059head:

alias int[] MyArray;
void main() {
    MyArray arr;
    foreach (i, item; arr) {}
}



This doesn't compile:

import std.typecons: Typedef;
alias Typedef!(int[]) MyArray;
void main() {
    MyArray arr;
    foreach (i, item; arr) {}
}

DMD 2.059head gives the error:

test.d(5): Error: invalid foreach aggregate arr


This simpler code gives the same error:

import std.typecons: Typedef;
alias Typedef!(int[]) MyArray;
void main() {
    MyArray arr;
    foreach (item; arr) {}
}


My main use cases for typedef are with arrays. So this problem makes
std.typecons.Typedef not much useful.
