',' certainly is an arithmetic operator that returns a result, just as much as ?: does (you can describe them just the same way) - and for that matter '=' (assignment - particularly in the sh context where there are no data type conversions to be concerned with). Further, while ',' does imply sequencing of its operands (as does && and ||) it has nothing whatever to do with control flow, or goto (even less than ?: which is certainly an included operator in sh). Re: 3631, "the spec should make it clear what operators are supported" - if it did it that way, and only listed the supported operations, and simply said that all other C operators are unspecified, that would be fine. But excludig explicitly all the ones that we could think of to exclude, but not the ones that were forgotten, makes it unclear what the status would have been had it been remembered, would ',' have been listed as supported or not (after all, ksh - all variants I could find to test it - supports it, and as we keep being told, ksh88 forms the basis of the posix sh spec.)
