This is an enhancement, not "rejects-valid".
Because foo.a is an expression, and it is neither type nor symbol.

http://d-programming-language.org/declaration.html AliasDeclaration allows type or symbol as the first argument.

If foo.a is not a symbol, why does alias foo.a b; compile without an error?

Now compiler treats foo.a as Foo.a, and Foo.a is a symbol. I think this is "accepts-invalid" bug.
