Avoiding Hash Lookups in a Ruby Implementation

I had an interesting realization tonight: I'm terrified of hash tables. Specifically, my work on JRuby (and even more directly, my work optimizing JRuby) has made me terrified to ever consider using a hash table in the hot path of any program or piece of code if there's any possibility of eliminating it. And what I've learned over the years is that the vast majority of execution-related (as opposed to data-related, purely dynamic-sourced lookup tables) hash tables are totally unnecessary. Some background might be interesting here.

Hashes are a Language Designer's First Tool
