Comment 21 for bug 1335323

How do you know you're outside the scope of a wider with-asdf-cache? Or do you first bind *asdf-cache* to nil then use with-asdf-cache to bind it to a hash-table? That's ugly. And what do you put in your RETRY?

If what you want is clear some cache lines, by golly, clear those cache lines! And if you believe there should be no negative caching, apply my patch — but I believe negative caching within a local session is usually a good thing.
