No, I hadn't. Thanks for the pointer. It's nice to see that it's quite similar to mine :-) > This word is in alien.syntax > because we generally only use it when interfacing with C libraries.

I was looking at having an array of actions indexed by symbolic constants, so I did need consecutive numbers. Having said that, a hashtable indexed by symbols, or a generic function dispatching on singletons, would probably do the same job. I suspect I was just letting C-based coding habits (where an indexed array would be distinctly faster) rule my design. I may still try it, just to get a feel for relative performance... (Hmm, for experiments like this, in C I might well write the 3 versions of the code using #ifdefs and use -Dxxx at compile time to build the 3 variants, to test them. What would be an idiomatic way of doing something similar in factor?)
