Doesn't look *that* sparse to me... I think the 8-space 
indentation give a false perspective. E.g. this is actually 1 
line longer, but looks denser:

package string translateFunction (string result, string name, 
Parameter[] parameters, bool variadic, String context)
{
     context ~= result ~ ' ' ~ name ~ " (";

     string[] params;
     params.reserve(parameters.length);

     foreach (param ; parameters)
     {
         string p;

         version(D1)
         {
             p ~= param.type;
         }
         else
         {
             if (param.isConst)
             {
                 p ~= "const(" ~ param.type; ~ ')';
             }
             else
             {
                 p ~= param.type;
             }
         }
	
         if (param.name.any)
         {
             p ~= " " ~ translateIdentifier(param.name);
         }
         params ~= p;
     }

     if (variadic)
     {
         params ~= "...";
     }

     context ~= params.join(", ") ~ ')';

     return context.data;
}
