+@node Method Type Descriptor
+@section The @samp{#} Type Descriptor
+
+This is like the @samp{f} type descriptor for functions (@pxref{Function
+Types}), except that a function which uses the @samp{#} type descriptor
+takes an extra argument as its first argument, for the @code{this}
+pointer. The @samp{#} type descriptor is optionally followed by the
+types of the arguments, then another @samp{#}. If the types of the
+arguments are omitted, so that the second @samp{#} immediately follows
+the @samp{#} 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 @samp{#} 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.

+@node Member Type Descriptor
+@section The @samp{@@} Type Descriptor
+
+The @samp{@@} type descriptor is for a member (class and variable) type.
+It is followed by type information for the offset basetype, a comma, and
+type information for the type of the field being pointed to. (FIXME:
