Thank you. Now we have something to work on. The program above produces 
the following error:

Error: no identifier for declarator Pragma!"help, this does not 
work!!!!!!!!!"

The error is fixed by adding a mixin:

     mixin Pragma!("help, this does not work!!!!!!!!!");

Despite another error it actually works:

hello
help, this does not work!!!!!!!!!    <-- IT WORKED
Error: t!() has no effect

The second error is fixed by another mixin:

     mixin t!();

Perhaps the example is too simplistic. Still, let's stay with it for 
further issues.
