ddoc crossreferences

[Morusaka]

I think I've find a way to make it work (with CandyDoc at least)

I've definied the following macro:

/**
  * Macros:
 * DDOC_PSYMBOL = <a name="anchor$0" id="$0"></a><span class="currsymbol">$0</span><script>explorer.outline.addDecl('$0');</script>
 */

and when I want a link to some definition, I've to write a line like this:

// immagine you want to link to opEquals
 /**
  *
  * See_Also:
  * $(LINK2 #anchoropEquals, opEquals)
  */
