  21    <p>For any of the symbol descriptors representing procedures, after the
  22 symbol descriptor and the type information is optionally a scope
  23 specifier.  This consists of a comma, the name of the procedure, another
  24 comma, and the name of the enclosing procedure.  The first name is local
  25 to the scope specified, and seems to be redundant with the name of the
  26 symbol (before the <code>:</code>).  This feature is used by GCC, and
  27 presumably Pascal, Modula-2, etc., compilers, for nested functions.
  28
  29    <p>If procedures are nested more than one level deep, only the immediately
  30 containing scope is specified.  For example, this code:
  31
  32 <pre class="example">     int
  33      foo (int x)
  34      {
  35        int bar (int y)
  36          {
  37            int baz (int z)
  38              {
  39                return x + y + z;
  40              }
  41            return baz (x + 2 * y);
  42          }
  43        return x + bar (3 * x);
  44      }
  45      </pre>
  46
  47 <p>produces the stabs:
  48
  49 <pre class="example">     .stabs "baz:f1,baz,bar",36,0,0,_baz.15         # 36 is N_FUN
  50      .stabs "bar:f1,bar,foo",36,0,0,_bar.12
  51      .stabs "foo:F1",36,0,0,_foo
  52      </pre>
