The problem is that you have a wide-character comma (，) there.
This works:
void main() {
writeln(["一", "二"]);

There is module 'static this()' for such runtime initialization:
Config config;
static this()

config = new
I'm not sure why you'd want to wrap the .offsetof expression in
a template, but it can easily be done like this:
enum offsetOf(alias A, string S) = mixin("A."~S~".offsetof");
Keep in mind that D's offsetof is flawed - if the object does not
contain the requested member, but implicitly convert

Wow! That is the case.

Sorry, I don't understand what exactly you are trying to do. :( Is
config file a compile-time concept? Do you want to read it at compile time?

I am tying to hardcode name of config file name. Then I would
read and parse it.
An exceptionally generous offer! May take you up on that. Thank
you :).

That is understandable: Since the console is set to 936, it
