Perhaps with something other than a range then. There are some uses in 
Phobos:

std/algorithm.d:        foreach (i, _; args)
std/exception.d:        foreach (index, _; FieldTypeTuple!C)
std/typecons.d:        foreach (i, _; Tup1.Types)
std/typecons.d:        foreach (i, _; Tup1.Types)
std/typecons.d:                foreach (i, _; Types)   // Rely on the 
field layout
std/typecons.d:            foreach (i, _; Types)
std/variant.d:        foreach (i, _; params)
