[aspectl-announce] AspectL 0.6.2

[Pascal Costanza]

Hi,

I have just released AspectL 0.6.2. See 
http://common-lisp.net/project/aspectl/

It contains the following changes:

* Special classes need a special default superclass in order to work. 
For convenience reasons, it is implicitly added to a class definition 
so that programmers don't need to worry about that default superclass. 
However, in previous versions of AspectL, I have made a few mistakes 
here: Forward referenced classes were not handled correctly, and under 
certain circumstances invalid class hierarchies were created. These 
mistakes are now fixed, thanks to a fruitful discussion in 
comp.lang.lisp with Marco Baringer, Bruno Haible, Simon Katz and Kenny 
Tilton. Special thanks go to Bruno Haible for insisting on leaving 
COMPUTE-CLASS-PRECEDENCE-LIST alone and to Simon Katz for the idea of 
how to handle forward referenced classes by fixing the list of direct 
superclasses after they have been changed to "real" classes. AspectL 
now also provides two functions INITIALIZE-CLASS-METAOBJECT and 
REINITIALIZE-CLASS-METAOBJECT in the AL.CLOS-MOP package that 
implements all the necessary machinery to make these things work and 
that you can reuse for your own metaclasses.

* LispWorks uses :default-initargs instead of :direct-default-initargs 
for the direct default initialization arguments of a class, contrary to 
what AMOP specifies. I have added the necessary conditionalization in 
al-mixins.lisp. Since I mainly use LispWorks, I have also erroneously 
used CLASS-DEFAULT-INITARGS instead of CLASS-DIRECT-DEFAULT-INITARGS. I 
have also fixed this.

* ...and a few other minor changes to internal class names and 
conditionalization code.
