The idea is to speed up string lookups. Currently the a-list maps strings to values, which means I must use assoc to search it. If it mapped symbols to values instead, I could use the faster assq. I'd rather intern the strings once and have done, but I don't want to cause a memory leak. Furthermore, the string I'm looking for is sometimes derived from symbol->string, so I actually have a symbol to start with. This is probably true for the majority of lookups, though not the majority of entries.
Ah, OK. When you spoke of "random" symbols, I had a fear you were generating symbols with (eg) sequential numbers as names or something similarly meaningless, just to get a 'comparison token'.
