Still, the type of a variable would determine whether whether
it's iterable.
As an improvement, the following program can be changed to call
use() recursively to visit all members of e.g. structs (which
can be determined by 'is (T == struct)').
import std.stdio;
import std.traits;
void use(T)(T var, size_t indent = 0) {
static if (isIterable!T && !isSomeString!T) {
foreach (i, e; var) {
writefln!"%*s: %s"(indent, i, e);
}
} else {
writefln!"%*s"(indent, var);
}
}
void main() {
int i = 42;
string s = "hello";
double[] arr = [ 1.5, 2.5, 3.5 ];
use(i);
use(s);
use(arr);
}

Very good! Thank you!
