           Summary: .dup for associative arrays
           Product: D
           Version: 0.178
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: enhancement
          Priority: P3
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: thecybershadow gmail.com


Since associative arrays are reference types, the language currently doesn't
provide a straight-forward way to duplicate an associative array. As a small
enhancement towards general language consistency, I would like to suggest a
.dup property, like for dynamic arrays, which returns a copy of the associative
array.

I second that.  I was surprised to find out just now when the compiler told me
it didn't exist for AAs.
(Is there a workaround?  Does  assigning to another AA make a copy?)

The "workaround" is:
foreach(key,value;aa1)aa2[key]=value;
This can easily be made into a template function.
