You say singleton I think wrong.
Use free-functions and globals instead.
Singletons are always a code smell that OOP based languages
like to say are a 'good thing'.
e.g.
module taskmgr;
import task;
private __gshared {
Task[] tasks;
}
Task[] getTasks() {
return tasks;
}
void clearTasks() {
tasks = null;
}
void addTask(Task t) {
tasks ~= t;
}
Sure, that works too, Thanks. However, we could leave the debate
about the pros and cons of singletons for another day. That's not
what my question was about though.
