I would rather that ".." stay with intervals and "..." with generators. The mnemonics make more sense that way. Having ".." resemble the math op with the same meaning, intervals, is a good thing. Besides comparing ranges, an interval would also often be used for a membership test, eg "$a <= $x <= $b" would alternately be spelled "$x ~~ $a..$b" for example. I would imagine that the interval use would be more common than the generator use in some problem domains. -- Darren DuncanThread Previous | Thread Next
