           Summary: Undocumented mangling of struct value

Consider the program:

----------------------------------------
module y;
template fffff(alias s) {
    void fffff() {
    }
}
struct U {
    int v;
}
void main() {
    fffff!( U(4) )();
}
----------------------------------------

The mangled symbol of fffff!( U(4) ) is:

    _D1y20__T5fffffVS1y1US1i4Z5fffffFZv

which means

    _D          (MangledName)
      1y        (LName: y)
      20__T     (TemplateInstanceName)
        5fffff  (LName: fffff)
        V       (TemplateArg: value)
         S      (TypeStruct)
          1y    (LName: y)
          1U    (LName: U)
         S1     (***UNDOCUMENTED*** struct value with 1 argument)
           i4   (integer: 4)
        Z       (end of TemplateInstanceName)
      5fffff    (LName: fffff)
      FZv       (TypeFunction: void _())

Above, the mangling

Value:
     'S' Number Value...

is not documented at all. The D spec should mention it.

(Also, the spec should also mention 'A Number Value...' can represent associative array literal as well.)

Demangling for struct literals have been implemented in commit 434e, and that of associative array literal in commit cbc4.
