The `#' Type Descriptor
=======================

   This is like the `f' type descriptor for functions (*note Function
Types::.), except that a function which uses the `#' type descriptor
takes an extra argument as its first argument, for the `this' pointer.
The `#' type descriptor is optionally followed by the types of the
arguments, then another `#'.  If the types of the arguments are
omitted, so that the second `#' immediately follows the `#' which is
the type descriptor, the arguments are being omitted (to save space)
and can be deduced from the mangled name of the method.  After the
second `#' there is type information for the return type of the method
and a semicolon.

   Note that although such a type will normally be used to describe
fields in structures, unions, or classes, for at least some versions of
the compiler it can also be used in other contexts.
