Perhaps you can wait until SRA runs, and then just DTRT for objects that

Alias structured are never SRA'd.

Certainly, in Dan's example:

x = a.f
c = a.e
a.e = 5
c = a.f

it should be possible to SRA "a" without any alias information at all,

Yes, you could, if you effectively ignored what the SSA infrastructure tells you (that they do overlap), and try to figure it out on your own.

This seems like a bad idea, IMHO.
