All classes (and interfaces I think), at root of inheritance have `Object` class, this class defines couple of generic methods, you can find this class in object.d btw. One of those methods is `bool opEquals(const Object rhs) const`, therefore if you try to call opEquals, it could be possible that in some cricumstances instead of your overload, one defined on Object is picked up, which checks only if rhs is same object as the one invoked upon. Btw, dunno how the rules for overload set resolution on opEquals work, so someone else should check whther this is a bug or expected behavior. Best regards, Alexandru.

They should not be accessible to anyone outside of those projects. So, it's pretty weird that it's up on the website, but my guess is that someone put it there so that the folks working on the code base could see the rendered ddoc comments for that code. For instance, I could believe that the dmd section there is there just to make it easier for some of the folks working on the compiler to more easily get an overview of the public symbols within those modules. But if you're not contributing to those projects, there really isn't any reason to see those modules. - Jonathan M Davis

You can use std.conv.toChars:

D Phobos Library Documentation: What is the Internal API for?
This is pretty basic question. If you open [D Library Reference](https://dlang.org/phobos/index.html) you are bound to see the **Internal API** section in the table of content. What is the **Internal API** (internal.core, dmd, rt) for and when, how and where to use it?

Most of the functions inside `std.conv` seem to be dependant on
[Garbage Collection](https://dlang.org/spec/garbage.html).
And I couldn't find a straightforward way to produce a `string`
value out of `uint` value.
How to convert or parse `uint` value to a `string` in `@nogc`
way?
You can use std.conv.toChars:
```d
void main() @nogc
{
int n = 515;
import std.conv;
char[10] s = 0;
auto r = n.toChars();
assert(r.length < s.length);

foreach (c; r)

import core.stdc.stdio;
puts(s.ptr);

Dunno if this might help, but I noticed that `==` sometimes calls `opEquals(const Object) const` instead of overload defined on class/interface, you might try and override it as well, and delegate to your overload that deals directly with `IOpt`. Best regards, Alexandru. Thangs Alexandru, It works. ...but why?
