Anonymous method shortest syntax

Regarding anonymous methods, and given a method "WriteConditional" that has the first parameter as a Func, is there a way to even eliminate the extra "() => " syntax?

It seems like you should be able to, since its unambiguous as long as there's no additional overload that would accept string, right?

void Program()
{
  IDictionary<string,string> strings = new Dictionary<string,string>() { {"test","1"},{"test2","2"}};

  //seems like this 'should' work, because WriteConditional has no other overload
  //that could potentially make this ambiguous
  WriteConditional(strings["test"],"<h3>{0}</h3>");

  //since WriteConditional_2 has two overloads, one that has Func<string> and another with string,
  //the call could be ambiguous, so IMO you'd definitely have to "declare anonymous" here:
  WriteConditional_2(()=>strings["test"],"<h3>{0}</h3>");      
}

void WriteConditional(Func<string> retriever, string format)
{
   string value = retriever.Invoke();
   if(string.IsNullOrEmpty(value)==false)
      Console.WriteLine(string.Format(format,value));
}

void WriteConditional_2(Func<string> retriever, string format)
{
   string value = retriever.Invoke();
   if(string.IsNullOrEmpty(value)==false)
      Console.WriteLine(string.Format(format,value));
}

void WriteConditional_2(string value, string format)
{
   if(string.IsNullOrEmpty(value)==false)
      Console.WriteLine(string.Format(format,value));
}
