    I'd move the sigh away from any hardship involved in using the raw DDE
messages onto the application developers that have believed that DDEML would
make DDE easier. Debugging a DDEML application requires understanding both
DDEML and the underlying DDE messages because that is the level on which the
debugging tools like DDESpy work reliably and is also how most servers are
documented. DDEML calls map almost 1:1 onto DDE calls/messages and provide
no real benefit in terms of producing a higher level interface.

    Among the many programs that use DDEML rather than rolling their own
more robust DDE are useful applications like PythonWin and Mozilla and hence
Komodo.
