You don't even need to convert it all to a struct. Since having 
function-nested unittests is just a parser issue, you can do this:

-----
int foo()
{
     static int bar()
     {
         return 42;
     }

     struct _
     {
         unittest {
             assert(bar() == 42);
         }
     }

     return bar();
}

However 'bar' must be marked static in order for this to work.
