there is also this usage:

I think this is a very uncommon usage. I think I have not used it so far.
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)
Because _ is not a language feature, this identifier is actually less
common. The prevailing one in Phobos is:
foreach (i, Unused; ...)
std/algorithm.d:7
std/array.d:1
std/datetime.d:1
std/parallelism.d:2
std/range.d:28
std/typecons.d:3
This is actually used more than any uses of 'foreach (_;' (2 uses) or
'foreach (Unused;' (10 uses) in Phobos! This is true even if we treat
std.range as an anomaly. (I also tried a case-insensitive search).
