Yeah, TypeInfo.{getHash,equals,compare} aren't implemented for 
TypeInfo_AssociativeArray, TypeInfo_Function and TypeInfo_Delegate in 
either Phobos or Tango. And all of those are required for the relevant 
types to work correctly as AA keys, IIRC.

Of course, you could implement them and attach the patch to the relevant 
bug report... which didn't exist yet.
Remedied that last part:
