I want to create a function threading() to run some function in 
other threading, but I get this error bellow. How can I get 
success?


Error: static function Programa.threading.Task!(fun).Task.impl 
cannot access frame of function Programa.threading
Error: template instance `Programa.threading.Task!(fun)` error 
instantiating

This works:

import std;
import core.thread;

auto threading(void function() fun){ return 
task(fun).executeInNewThread(); }

void main(){
    writeln("Main: ", thisTid);
        threading({ writeln("Hello, ", thisTid); });
}
