TBH, opApply is much better suited to classes.
But in order to have multiple parameters with foreach by using
a range, you must return a tuple:
auto front() { import std.typecons: tuple; return tuple(index,
_app.data[index]);}
Note, do NOT do this on your class, you should be creating a
range struct type, and return the range from opIndex() with no
parameters.

I'm using this, thanks for all. Can someone clarify how does
opApply() works? I assume it's called every iteration and as
opApply() has a loop does it means the number of iteration ran
actually is the ones from foreach() is 2*n where n is the number
of elements in the array, is this right?
