I'm still adjusting to the idea of AAs as part of the language
rather than library. Not sure I like it, but on the other hand
it doesn't really hurt. The foreach construct isn't any better
(or worse) than C++'s, unless I'm missing something (which is
very possible). But slices are awesome!
In D you can `foreach` over a list of types (AliasSeq) at
compile time, not just over ranges at runtime. (For the moment,
it's still only available in function bodies though, unlike
`static if`.)
Neat! I didn't know that. You can do that in C++, but in typical
fashion not with a convenient foreach statement. You have to do
some crazy type list recursion stuff.
So chalk up another point for D's "ease of metaprogramming" :).
