--- Comment #4 from [email protected] 2013-08-05 13:41:39 PDT --- There are other considerations as well. Let's say we are calling iota(start,end,inc). Let S=typeof(start), E=typeof(end), I=typeof(inc), C=CommonType!(S,E). Then: 1) Ideally, as long as C.init<end is a valid expression, and start+inc is convertible to type C, then iota(start,end,inc) should be supported. 2) Should we optimize iota(start,end,inc) in the case that I supports integer multiplication? That is to say, if n is an integer, and n*inc (or inc*n) is a type that can be added to values of type C, then we could potentially return a random access range wherein opIndex returns start + i*inc as long as the result < end (we can throw a RangeError if result !< end). This might be a nice optimization for things like BigInt in some cases. 3) If start+inc is *not* supported, but start++ is, then should we support iota(start,end)? 4) If start+inc is *not* supported but start-- is, and end < start, should we support iota(start,end)? -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
