Example.
I want to find the index of an item in an array.
```
import std.stdio;
import std.string;
void main()
{
string text = "Hello, World!";
string searchSubstring = "World";
ptrdiff_t index = text.indexOf(searchSubstring);

Why was it so hard to find?
What is the best way to search for a function
in the Phobos library?

What’s the current lib implementation like?
It is amortized O(1), like most hash implementations.

Well, you if you use dup, you're asking for a mutable array,
whereas if you use idup, you're asking for an immutable array.
Yes, `idup` may be needed e.g. for overloads varying on
mutability.
Whether the result of dup is then

I think you meant `idup`? `dup` will make it mutable.
