Can you explain me, where here a double context is needed? Because all

I believe D's type system isn't smart enough to see independence
between context and closure, otherwise your original example would also
work as users and servers are context independent.
What about:
```D
string doSomething(string[] servers, string user) {
return user ~ servers[0];
}
void main() {
static servers = ["s1", "s2", "s3"];
static users = ["u1", "u2", "u3"];
static lambda = (string user) => servers.doSomething(user);
writeln(map!(user => servers.doSomething(user))(users));
writeln(taskPool.amap!(lambda)(users));
}
```
That looks nice, but unfortunately my data for servers and users in the
real world is not static but comes from a config file.
