It can't happen until more work is done on the compiler's treatment of 
opEquals().

Note that there will be a large amount of work in removing it from the 
compiler. Moving AAs from the compiler to the runtime was horrific in 
terms of the subtle regressions it caused -- and it already used runtime 
calls for every operation it supported. Complex will be much, much worse.
