It seems it would be more readable to have "static foreach" and simply put a

I agree. I have recently written about it:
http://www.digitalmars.com/webnews/newsgroups.php?art_group=digitalmars.D&article_id=107873
If you see at this document (about half of those ideas are now present in D2)

At page 52 you can see that Walter&Andrei too were appreciating the idea of a
static foreach. So I presume you will see it in D3 or even sooner :-) I presume
it's not a hard thing to implement. But Walter is busy, and Andrei's book was
already late.
Bye,

static foreach was part of the plan until recently, but Walter
encountered severe implementation difficulties so we had to abandon it.
I agree that it's odd that the same statement iterates at compile-time
or run-time depending on the iterated type.
