[Openmcl-devel] type specifier '(simple-vector n) in defmethod

[Shannon Spires]

With respect to pattern matching I hear good things about the Trivia 
library, which adds the capability to Common Lisp:

I haven't used Trivia, but if it is as good as it seems, it shouldn't be 
necessary to add it to Common Lisp itself. Likewise with your (David's) 
Actor system, which is excellent.

As Ron says, the focus should be on the M1 port of CCL, and supporting 
its users afterward. Anything that can be added with a library should be.
