As a result "front" and "back" template functions from std.array don't compile,
isInputRange!(S[]) is false and none of range functions can work with an array
of structs with a const/immutable member.
immutable struct IS { int t; }
struct S { immutable int t; }
void f(ref S) { } //compiles
ref IS f() { return IS(); } //compiles too
ref S f() { return S(); } //doesn't compile
void main() {
static assert( isInputRange!(S[]) ); //as a result assertion failure
}
