( #3333=superdoc: print w/replies, xml ) Need Help??

The main reason I tend to use map is to signal to the reader of the code that this is an operation on a list not just on a set of values that are conveniently represented as an array.

In other words, to me, map and grep carry extra semantic value to future maintainers of the code. (In most cases, Wade-future does not really remember what Wade-past had in mind.<grin/>)

To me, your first example implies that we are transforming a list. The second implies we are transforming the elements of a list. Although the results are the same to the computer, to the programmer the meaning may be very different.

    [Corion]: I've started that again this month (now forever instead of a limited time), and it already destresses me a lot
    [holli]: There are Anti Vaxxer weeks at IKEA.
    [Corion]: Of course, it's a 20% cut in the money I receive, while the work doesn't necessarily reduce at all, but my approach is to make the work take longer instead of fitting 5 days worth of work into 4
    [holli]: 50% off all children coffins.
    [Corion]: holli: Ooof :)
    [hippo]: Cut should beless than 20% after tax, though. :-)
    [Corion]: hippo: Yeah, but at least two years ago, it still was close enough to 20% cut
    [Corion]: But I have a very positive experience with a four day workweek and a three day weekend. I can't easily go back though to full money.
    [Corion]: That is easy without having to pay for a house, a wife or children though. If I had any of these, or any two of these, the decision wouldn't be that easy.
    [ambrus]: wait. I understand no wife and children, but how do you not have to pay for a house?
