Attached is a patch ported from cmucl-imp 2001-03-19, by Ray Toy,
Here is a patch that implements defoptimizers for array-element-type
and coerce. I think array-element-type does the right thing in all
cases. The optimizer for coerce isn't quite as smart as it could be
but it solves the case that Paul was asking about. This could use
o Add defoptimizers for array-element-type and coerce.
I've attached some demo-code to see the effects of that, too.
Just do a DESCRIBE on these functions, and the return values
should speak for themselves.
