What's the difference between static class and static struct?
What should i use?
__traits(allMembers, mixin(__MODULE__)) also yields a module name
like object, but then how can you find out that object is a
module?
This doesn't work:
void main() {
pragma(msg, is(int == int));
pragma(msg, is(object == module));
}

Non-static structs/classes have an extra pointer. Static ones
don't have it, so their differences are the usual ones: a class
is used by reference and

At the moment it goes straight go code.dlang.org, which may be a
bit overwhelming if you have just arrived at dlang.org and want
to see what it can do.
Is it worth changing to the library wiki write up page on
