Indirect function calls [...] have never been blindingly fastActually, in my measurements correctly predicted indirect calls have been as fast as direct calls on Intel-compatible CPUs for a decade or two. That obviated the need for inline caching, so it's not surprising that all the papers on inline caching are more than two decades old.

In large applications the indirect branch predictor runs out of capacity so inline caches are still very useful.
