The lack of optimization in CLOS has long been a sore point.

Here are some related reads.

PC seems to argue that sealing is not necessarily helpful for 
optimization.  I tend to agree, but would still argue that a naive 
compiler might only try inlining things that are sealed.

Sealing may also be close to what the Racket community wants.  They 
dislike the "growth by mutation" nature of CLOS, and the uncertainty that 
comes with it.
