• Leandro Motta Barros (24/24) Nov 30 2013 Hello,
• Shammah Chancellor (4/41) Nov 30 2013 DMD version? Can you post a reduced example which produces the error.
• Leandro Motta Barros (6/48) Nov 30 2013 I am terribly sorry, this was a completely lazy question.

Hello,

I my FewDee game prototyping library (https://bitbucket.org/lmb/fewdee) I
ignored most of the usual reccomendations like "be careful with the GC,
it's slow" and "associative arrays are buggy in D, so avoid them". I just
used whatever I found convenient to have my stuff running with minimal
effort.

So, I did something that may be an abuse of D's associative arrays:

alias
  Tuple!(const(GameState), ALLEGRO_EVENT_TYPE)
  stateTypePair;

// GameState is a class, ALLEGRO_EVENT_TYPE is
// some integral data type

EventHandler[EventHandlerID][stateTypePair]
   _eventHandlers;

// EventHandler is a delegate. EventHandlerID is
// an integral type.

This used to work (surprisingly? :-) ) until very recently (when I upgraded
to DMD 2.064, it seems).

Now, I am getting this

   object.Error: TypeInfo.compare is not implemented

when I try to use my '_eventHandlers' AA.

So, any suggestions?

Thanks a lot!

DMD version?  Can you post a reduced example which produces the error.  
I can't tell where a typeinfo would be getting used from that example.

So far, I couldn't reproduce the problem in a small example. I'll look
deeper into this before posting again about it.
