I guess we have to change clang codeGen for this anyway.
Not sure which has less impact for codeGen side, lvalue like what is in the
current patch or make it a lvalue reference? My feeling is lvalue reference
might be eaiser.
Did you test what needs to change for clang codeGen on top of the current patch?
