Good example, thanks for the information.

Maybe the compiler can do more works to make the code more readable. Here are my examples:

template EventHandler(T=Object)
{
   alias EventHandler = void delegate(T sender);
}


void test01(EventHandler handler) // Error
{
  // It's what I want. However, it doesn't work.
}

void test02(EventHandler!() handler)
{
  // It works. Howerve, it ...
}

void test03()(EventHandler handler)
{
  // It works too. Howerve, it ...
}

void test04(EventHandler!string handler)
{
  // It's OK.
}

If you want, take a look at dtemplate.d in the compiler source. :)
I would advise to do this when well rested and motivated.
