Is it bad for object.di to depend on core.exception?

Not just comparisons, but size of values, etc., all need typeinfo
currently. Pretty much all the code in aaA.d needs to dig under the hood
and do lots of black magic like pointer arithmetic based on typeinfo
stuff in order to do stuff. Perhaps _aaLen might be the only exception.
While it's cool that D lets you do this when needed, it's also a sign
that some cleanup might be in order. :-)

How feasible is it to migrate AA's into object_.d, say, and have the
stuff in aaA.d simply wrap around AssociativeArray? I suppose this can't
really happen without some major changes in the compiler, since I don't
know how to instantiate AssociativeArray given only the typeinfo's (not
the actual types) of the key/value.
