Both a bug, and you're doing something wrong.  CTFE should be giving you a 
'cannot read static variable at compile time' error.

Try this:

import std.traits;

class ModInfo {

}

const(ModInfo) moduleInfo(alias MODULE) = new ModInfo(); // 1

const(ModInfo) getModuleInfo(alias mod)() {
static if(__traits(hasMember, mod, "__module_info")) {
return __traits(getMember, mod, "__module_info");
} else {
return moduleInfo!mod;
}
}

void main() {
static const(ModInfo) info = getModuleInfo!(main);
}

The 'unique ModInfo per module' is done by the templated variable 1.
