Static foreach internal variable

[Andrey via Digitalmars-d-learn]

Hello,
is it possible to declare an internal variable in "static 
foreach" and on each iteration assign something to it?
Example:
static foreach(arg; SomeAliasSeq)
{
   internal = arg[0].converted;    // a shortcut for expression 
"arg[0].converted"

   static if(internal.length == 0) { ... }
   else static if(internal.isNull) { ... }
   else { ... }
}
