I though the primary use of static foreach was to force the
compiler to attempt compile-time iteration even for
non-TemplateArgList arguments like arrays known at compile-time

e.g.

static foreach(el; [1,2,3,4])
{
      pragma(msg, el);
}

or

static foreach(el; 5 .. 8)
{
      pragma(msg, el);
}


The mixin template example I gave is already a "static" foreach,
just not explicitly so.
