Yes, areduce would be nicer if it looked like a binding set:
(areduce [aname anarray, ret init] expr)
(areduce [aname anarray, ret init, start-idx start-n] expr)
(areduce [aname anarray, ret init, start-idx start-n, end-idx end-n]
expr)
Treating amap similarly is slightly different since you don't supply
an initial value for ret.
You can put up an issue for this if you like.
