I never said they should not evaluate expressions. Expressions are always 
evaluated in any context in D, but they are immediately converted to values 
(so long as they are evaluable). But for this very reason, alias sequences 
can not "contain" or "encapsulate" expressions in un-evaluated form in any 
way (unlike, say 
http://docs.sympy.org/dev/modules/core.html#sympy.core.mul.Mul) in that the 
components of the expression are lost by the time the AliasSeq gets defined.
