Static loops

To me it seems odd that we have a static if but no static while
or static for or static foreach.
Basicly all a static loop would do is unroll itself at compile
time. The only reason I want this is that currently it is
impossible to use a loop variable in any sort of complietime
expression such as a static if or a template instantiation.
Was/is something like this planned? Is there a way to get similar
functionality now? So far the only way I have found to insert
loop variables into a compile time expression is to use a side
function to do looping and generate a string for mixins, which is
very very very ugly, am I missing somthing?
I saw one thread from 2004 about the same thing with very little
replies...

[Edit]
Ok before I posted this, I did a few more tests and it seems like
foreach has this capability somewhat, which is just confusing.
Using foreach on a tuple causes it to be evaluated at compile
time, which is nice but confusing. Come to think of it, I don't
know how you would loop over tuples otherwise...
