Naming member functions/methods with a single underscore, good style or bad?

In some languages where you cannot override the () operator, I have seen methods with a single underscore, usually for 'helper' classes. Something likes this:

class D10
{
   public function _()
   {
     return rand(1,10);
   }

}

Is it better to have the function called Roll()? Is a underscore fine? After all, there is only one function, and it removes the need to look up the name of the class.

Any thoughts?
