 C++ Features

 C++ Features
 ============
 

-- Namespaces
-- STL containers compatibility
-- Exception Handling
+- Namespaces:
+    We want to have all wxWindows identifiers in "wx" namespace but provide
+    typedefs/#defines for backwards compatibility. This can be done easily
+    for the classes and the only real problem are the enums as they would
+    all have to be duplicated at both the global scope (with "wx" prefix) and
+    in wx namespace (without it)
+
+- STLization
+    This involves providing optional wxString implementation using std::string
+    and doing the same for all our containers with the exception of wxHashMap
+    which should simply be rewritten using templates (but keeping the old
+    version for backwards compatibility -- ideally wx 3.0 would still be usable
+    without templates, even if not all of its features would be available then)
+
+- Exceptions
+    We are not going to use exceptions in wxWindows itself but our code should
+    become exception safe. This is a very difficult task as it means that no
+    resource allocations (including memory, files, whatever) should be done
+    without using a smart pointer-like object to store the result as it is the
+    only way to prevent resource leaks in presence of exceptions
+
+- Real RTTI
+    Optionally use the real RTTI instead of wx emulation of it. Keep the
+    current stuff for backwards compatibility.
+
+- Complete replacing TRUE/FALSE with true/false
+    Trivial
+

 Core
 ====
 
 - use wxEventLoop in all builds

+    wxApp and wxDialog should use wxEventLoop objects (the exact class can be
+    customized by user code by overriding some wxApp::CreateEventLoop())
+    instead of duplicating the same code
+

 - remove wxCOMPATIBILITY (1.X)
 - remove wxCOMPATIBILITY (1.X)

-- Modularization/Build System/Project File Generation
-- RTTI native Support, Properties/Member-Metadata, 2-Step Init with virtual create
+    At least WXWIN_COMPATIBILITY and maybe WXWIN_COMPATIBILITY_2 code should be
+    removed from the library. wxDEPRECATED() should be used with everything
+    inside WXWIN_COMPATIBILITY_2_2. The stuff inside WXWIN_COMPATIBILITY_2_4
+    probably should not be deprecated (yet?) because this would give thousands
+    of warnings for the existing code.
+
+- Modularization/Build System
+    Candidates for components:
+        +   contrib widgets (and maybe some of the ones currently in the core)
+        +   wxHTML
+        +   network stuff
+        +   printing (?)
+        +   ODBC classes
+        +   ...
+
+- Project File Generation
+    We need a (GUI) tool to generate the project/makefiles for all supported
+    platforms/compilers. Not sure if it should be used for the library itself
+    (would be nice to have something like "make menuconfig" for Linux kernel
+     which allows you to navigate easily amon all of the configure/setup.h
+     options but there is a problem with distributing such tool as it can't be
+     compiled by the user because it is needed before the library is built) but
+    we definitely need it for the users makefiles.
+
+- Properties/Member-Metadata, 2-Step Init with virtual create
+    TODO: still unclear what do we need exactly
+
+- Tidy code and add comments to headers (preferably in
+  Doxygen/Javadoc style)
+
