     When compared to wxVariant, there are various internal implementation
     differences as well. For instance, wxAny only allocates separate data
-    object in heap for large (i.e. size in bytes more than
-    WX_ANY_VALUE_BUFFER_SIZE) or non-POD (Plain Old Data) data types.
-    Pointers, integers, bools etc. are fitted in the wxAny's internal buffer
-    without need for any extra allocation. It is possible that wxAny cannot
-    automatically determine if your own data structure is considered a
-    POD or not, so you may need to declare it as such explicitly, using
-    code like this:
-
-    @code
-    #include "wx/meta/pod.h"
-    WX_DECLARE_TYPE_POD(MyPodStruct)
-    @endcode
-
-    Be extra careful what you declare as Plain Old Data. It must be such data
-    that can be copied with memcpy() without corrupting program integrity. For
-    instance, POD structures usually cannot contain pointers or references to
-    other data. wxRect, wxPoint, and wxSize are good examples of POD
-    classes.
-
-    Note that pointers to any and all types are already automatically
-    declared as Plain Old Data.
