digitalmars.D.bugs - [Issue 22008] New: foreach over enum members

https://issues.dlang.org/show_bug.cgi?id=22008

          Issue ID: 22008
           Summary: foreach over enum members
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: b2.temp gmx.com

Given the declaration

---
enum E {e1, e2}
---

the following code

---
foreach (v; E)
{
    // use v
}
---

could be semantically equivalent to

---
foreach (e; __traits(allMembers, E))
{
    auto v = __traits(getMember, E, e);
    {
        // use v
    }
}
