[slime-devel] reporting SLIME errors from Lisp

[Taylor R Campbell]

What's the best way to report errors in SLIME that were detected on
the Lisp side, such as `no package FOO'?  Right now in SLIME48 I just
abort the RPC and log a message to the console about the error, but
this is suboptimal, because all the user sees is `Evaluation aborted'
or `Synchronous Lisp Evaluation aborted.'  Perhaps :ABORT responses to
RPCs could include optional error messages?
