The defun* is a CL compatibility macro and not a part of standard elisp.
i.e. you have to load the 'cl package to get it. 

Elisp can handle the &optional and &key parameter types in normal defun.
IIRC the only real difference is that elisp cannot set default values
for optional parameters - they are nil if not supplied and thats it. 

When you say edebug does not understand these forms very well, what do
you mean?
