digitalmars.D.bugs - [Issue 20617] New: There is no support for copying hashmaps in


          Issue ID: 20617
           Summary: There is no support for copying hashmaps in Druntime /
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: phobos
          Assignee: nobody puremagic.com
          Reporter: andrej.mitrovich gmail.com

void main()
    int[int] map1 = [1:1, 2:2, 3:3];
    int[int] map2;
    map2.copy(map1);  // ?

I am not asking for special syntax. Stuff like 'map2 = map1[]` would look cool,
but it's outside the scope here.

There should be `copy` functionality implemented somewhere in Druntime /
Phobos, it's not ideal that we have to write this code manually such as:

map1.byKeyValue.each!(pair => map2[pair.key] = pair.value);
