[swift-evolution] [Proposal] Disallow redundant `Any<...>` constructs

I don't understand what you mean. I definitely think your 'typealias ABC = Any<AB, C>' should be valid.
I said typealias ABC = Any<AB, C> is valid.
typealias AliasA = Any<A>
is not and furthermore
typealias AliasAA = Any<AliasA>
should also not be valid because Any<Any<A>> shouldn’t be valid.
IMO the rules around banning nested any are unnecessary complexity. The constructs have a well defined meaning. The argument to ban them is purely around limiting allowable syntactic style. People are very unlikely to actually use this nesting except through the abstraction of a typealias which is a very valid use case. The complexity of the rules does not appear to provide any tangible benefit.
Which rule(s) do you refer to exactly?
