Implement a !foreach operator analogous to GNU make's $(foreach).
Use it on dags and lists like this:
class decls {
string name;
}
def Decls : decls;
class B<list<string> names> : A<!foreach(Decls.name, names, !strconcat(Decls.name, ", Sr."))>;

<dd>If 'a' and 'b' are of string type or are symbol references, substitute
'b' for 'a' in 'c.' This operation is analogous to $(subst) in GNU make.</dd>
