Issue ID: 19981
Summary: std.algorithm.iteration.group fails when element type
has a const/immutable member
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P1
Component: phobos
Assignee: [email protected]
Reporter: [email protected]
```
unittest {
import std.algorithm.iteration : group;
static struct X {
const int x;
}
X[] arr = [X(1),X(2),X(3)];
group(arr);
}
```
Currently (DMD 2.086.1) this produces an unhelpful error: Error: cannot modify
struct instance `this._current` of type `Tuple!(X, uint)` because it contains
`const` or `immutable` members
