Re: Re: confirmation on :default-initargs not working?

There is PCL. I have considered porting that to replace the closette 
implementation. It is large but I believe it shouldn't be too difficult to 
port. I know other vendors have also begun with PCL, but then have spent a lot 
of time rewriting it and optimizing it. The sheer size deterred me before, but 
given all the work that has been done (much by you and others) to make Corman 
Lisp more ansi-compatible in  the last year would no doubt make the job easier.

I believe it is a full CLOS implementation, probably not ansi but more CLTL2 
level. I am not sure if it has the MOP support that Closette has, but I imagine 
good performance and full CLOS is more valuable than full MOP support at this 
point.

I originally started with closette based on a recommendation from a member of 
the MCL development team, who said they had such a problem with PCL that they 
felt it would have been better to begin with Closette. I don't even remember 
who told me that anymore. It is true that I know Closette now pretty well and 
have made many modifications to it, and remaining clos issues are not usually 
too hard to deal with. However, there are quite a few and obviously we haven't 
been able to improve it as fast as we should. I am not sure if the performance 
will ever be up to the level I would like without pretty much rewriting method 
dispatching. I am not sure how good PCL method dispatching is (after all it is 
"portable") without mods--it may need a lot of work as well. I am pretty sure 
using PCL would be a significant improvement, althought it would doubtless 
increase the lisp image size.

I looked into the :default-initargs issue. This looks like it was never fully 
implemented. Adding it looks to be a fairly simple job, and I will try to get 
to it soon and make a patch.
