          Issue ID: 18652
           Summary: hashOf example doesn't compile
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: regression
          Priority: P1
         Component: druntime
          Assignee: nobody puremagic.com
          Reporter: elpenguino+D gmail.com

The example in the documentation for object.hashOf does not compile.

```
struct Test
{
    int a;
    string b;
    MyObject c;
    size_t toHash() const  safe pure nothrow
    {
        size_t hash = a.hashOf();
        hash = b.hashOf(hash);
        size_t h1 = c.myMegaHash();
        hash = h1.hashOf(hash); //Mix two hash values
        return hash;
    }
}
```
This is entirely due to it being marked  safe, while hashOf(string) is  system.

This example should be made into a documented unittest and corrected.
