           Summary: std.typecons broken (or wrong documentation presented)
           Product: D
           Version: 2.014
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: arkangath@gmail.com


The example given in the example for defineEnum in page
http://www.digitalmars.com/d/2.0/phobos/std_typecons.html#defineEnum
does not compile.
The specific code is

import std.stdio;
import std.typecons;
mixin(defineEnum!("Openmode", "READ", "WRITE", "READWRITE", "APPEND"));
void main()
{
    Openmode m = Openmode.READ;
    string s = toString(m);
    assert(s == "READ");
    Openmode m1;
    assert(fromString(s, m1) && m1 == m);
}

But DMD (the latest 2.x version) claims that .toString does not exist. Was it removed or broken? Should the bug be filed has "inconsistent documentation" or "broken library"?

Lastly, why not put the .toString directly onto the enum structure? Going around with this mixin is just ugly.

The functions seem to have changed to "enumToString" and "enumFromString". The docs have not been updated.

Regular enums now support conversion to and from string, which makes defineEnum unnecessary. I deprecated it. http://www.dsource.org/projects/phobos/changeset/2051
