I was thinking if you did:

   $a = $b;

then the equal method for $a would return true if passed $b to compare 
with, regardless of the type.

Equality is a rather nebulous thing without context, though. Perhaps this 
should get a context passed in as a parameter.

We might have aliased variables or something, where two variable 
pointers  which point to two different variable structures are actually the 
same thing. Threads do this too in the current implementation. (And in the 
pthreads interface, though neither are a great argument for it...)
