Too much abstract freedom? N adjacent tree nodes, N neighbouring states, etc.

You have a chain, an ordered sequence. For each element, one property is defined: the successor.

    Hm. I'm not convinced by that argument.

    1. map is a piece of paper with colored lines and symbols; or the process of making one.
    2. reduce, is what you do to a good sauce or damaged goods.

    I think context and convention; along with conciseness and memorability are key here.

    For each element, one property is defined: the successor.

    Hm. Can you have a successor without a predecessor? And actually, this deals with both -- or potentially more:

    sub mapAdj(&$@) { local( $a, $b, $c, $d, $e, $f, $g, $h, $i, $j ); my( $code, $n ) = ( shift, shift ); map $code->( ($a, $b, $c, $d, $e, $f, $g, $h, $i, $j ) = @_[ $_-$n .. $_ ] ), --$n .. $#_; } my @accum = mapAdj{ $a + $b + $c } 3, 1..10;

    And 'successor' tends to have mathematical connotations which don't apply to a list of *any*things.

    For the simple case of adjacent pairs, I toyed with forByTwo() :)
