digitalmars.D.learn - Task when used on a function that takes parameters doesnt work.

Here is a test that I did:

void func(int i)
{
Thread.sleep(i.seconds);
}
void main() {
auto test = Task!func(3);
test.executeInNewThread();
test.yeildForce();
}

This gives the following errors(I'm using Code::Blocks as an IDE 
by the way, so this is what the IDE outputted):
d:\Programs\D\dmd2\windows\bin\..\..\src\phobos\std\parallelism.d|516|Error:
function `hello.func(int i)` is not callable using argument types `()`|

d:\Programs\D\dmd2\windows\bin\..\..\src\phobos\std\parallelism.d|516|      


hello.d|8|Error: template instance `std.parallelism.Task!(func)` 
error instantiating|


Any fix for this?

You have some typos there

import core.thread;
import std.parallelism;

void func(int i)
{
    Thread.sleep(i.seconds);
}
void main() {
    auto test = task!(func)(3);
    test.executeInNewThread();
    test.yieldForce();
}

 You have some typos there

 import core.thread;
 import std.parallelism;

 void func(int i)
 {
     Thread.sleep(i.seconds);
 }
 void main() {
     auto test = task!(func)(3);
     test.executeInNewThread();
     test.yieldForce();
 }


Typos: instead of Task you should write task, instead of  yeildForce you
should write yieldForce
