Language ref -> Array -> Slice
    "An array slice does not copy the data, it is only another reference to it."

So the total slice of a static array is a range using the underlying memory of the static array isnt it ?

yes

Thanks. On a sader note, I found a respons'less thread about my second question :

"where std.container.Array is concerned: how come I can't use a foreach(i, x; myArray) formulation?  I.e. one where the foreach can infer the index value as well as the contained value ..."

The index is the problem. Generally, foreach doesn't do automatic indices for ranges. You can use std.range.enumerate or count yourself explicitly.

foreach(i, t; myRange.enumerate) {...}

size_t i = 0;
foreach(t; myRange) {... ++i;}

Is it a compiler problem or a language restriction ? Thanks for the workaround btw, I will try it !

it is by design. `foreach` is not a "fancy for with hidden counter", it's more high-level construct. so if range isn't providing the counter, `foreach` will not guess why, and simply doesn't provide it too.
