size_t ndim(A)(A arr) {
return std.algorithm.count(typeid(A).to!string, '[');

Is there a way to find out the number of dimensions in an array
at compile time?

dimensionCount!string should be 2.
My take without std.traits:

enum rank = 1 + rank!U;

template rank(T: U[n], size_t n)

yeah.

Thanks everyone!
The solution that works for me now looks like this:
template ndim(T) {
static if (std.traits.isArray!T) {
static if (is(typeof(T.init[0]))) {
alias SubArrayType = typeof(T.init[0]);
enum ndim = ndim!SubArrayType + 1;
}
else

No, it isn't. Only structs and classes can have overloaded
operators.

You can create custom struct type with opCmp() and create enum
with that type. Example: https://run.dlang.io/is/m7DN66
