Re: Defstruct Extensions

[Gregor.pa@Xerox.COM]

Several of these functions exist in CommonLoops.  In addition, the
metaclass mechanism makes it easy to make Portable CommonLoops (PCL)
deal with a particular CommonLisp's defstruct types as "first class"
classes.

This means that if you have a version of PCL which has been "taught"
about the particular Common Lisp's local type system you can use the PCL
functions to get the information you need regardless of whether you are
asking about a type defined by defstruct or a CommonLoops class.


In CommonLoops:

GET-STRUCTURE-SLOT is called GET-SLOT

STRUCTURE-SLOT-NAMES is called ALL-SLOTS

MAKE-STRUCTURE is called MAKE



STRUCTURE-OPTION 
STRUCTURE-SLOT-OPTION

don't exist as named functions, but it might be a good idea to add them.
Of course, the only interesting part is making them setfable.
