N-dimensional slices is real world example where `static
foreach` would be useful.

Best regards,

The operator overloading and slicing mechanics look great, but
I'm probably more excited about the future work you have listed.
Some thoughts:
The top line of ndslice.d says it is for "creating n-dimensional
random access ranges". I was able to get the example for operator
overloading working for dynamic arrays, but it doesn't seem to
work for static. Hopefully this work can be extended. In
addition, hopefully the future work on foreach byElement will be
able to work on static arrays in addition to dynamic.
My second point seems to be related to a discussion on the github
page about accessing N-dimensional arrays by index. Basically
there are some circumstances where it is convenient to loop by
index on an N-dimensional array.
Finally, I have been trying to do something like
auto A = 4.iota.sliced(2, 2).array;
auto B = to!(float[][])(A);
without any luck. Seems to work though for one-dimensional
arraays. I think instead you have to do something like
auto A = iota(0.0f, 4.0f, 1).sliced(2, 2).array;
