           Summary: to!string(enum) returns incorrect value
           Product: D
           Version: D2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: zan77137 nifty.com



This code doesn't work:
--------- main.d ---------
enum E
{
    a = 0,
    b = 0,
    c = 1,
}

void main()
{
    import std.stdio, std.conv, std.string;
    assert(format("%s", E.c) == "c"); // main(11): OK
    assert(to!string(E.c) == "c");    // main(12): NG
}

--------- RESULT ---------
$ dmd -run main
core.exception.AssertError main(12): Assertion failure
---------

I think it is strange that to!string returns incorrect value though format
returns correct value.

Yeah, we went a bit overboard with avoiding allocations and ended up using
indexing, but forgetting we're calling NoDuplicates when generating the
switch/case.

 Fixing ASAP.


We could use __traits(getMember) unless you find another solution.
