Another usage is for testing parsers or string functions directly 
on the source. E.g in "devel" mode the main function

void main(string[] args)
{
     version(devel)
     {
         // dont mess with params, use the text in source to catch 
most simple bugs.
         File f = File(__FILE__, "r");
     }
     else
     {
         // load using args
     }
}

I'm for this, always absolute. Eventually forced by a new switch: 
default behavior is not changed.
