Hello, today I filed a bug on generalized-vector->list
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=12465 I remember similar bugs in the past, and I'm thinking that these functions are redundant since we have array-ref, array->list, and so on, which also work on strings, uniform vectors, etc. The only generalized-vector-? function that doesn't have a direct array-? correspondence is generalized-vector-length. However, even for arrays of rank > 1 it is often convenient to have a function such as (array-length a) = (car (array-dimensions a)) or maybe (array-length a) = (fold * 1 (array-dimensions a)) Personally I'd favor the first as there's nothing to compute, but either would work to replace generalized-vector-length. Possible objections: — generalized-vector-? may be marginally faster than array-? Both need to do a bunch of type checks and dispatching, and generalized-vector-? needs to check rank anyway, so I'm guessing this doesn't matter. We could do some benchmarking. — generalized-vector-? acts as an extra check on rank array-ref will flag rank errors, so this objection applies only to -length and ->list. I do not think this is important because it's usually clear from the code whether you're dealing with arrays of rank > 1 or not. But on this I'd like to hear from users of generalized-vector-?. TLDR, I propose to remove the generalized-vector-? functions since the array-? set can replace them. Regards, Daniel
