That is a very common confusion with ranges.

No, parts is a lazy range, which is ready to serve its elements as
needed. If you want to convert its elements to an array eagerly, you can
call std.array.array:
import std.array;
// ...
writeln("There are ", array(parts).length,
" numbers in line ", line_count++);

writeln(typeid(parts));
or
writeln(typeof(parts).stringof);
