std.typecons still has DDOC comments but is hidden from the 
public documentation (except a note on AliasSeq which we should 
probably be removed).

But I don't see much value in deprecating/removing TypeTuple 
because it's implementation just forwards to AliasSeq anyway and 
hence does not require maintenance/bugfixes.
