There's nothing quite like mapcar with regards to it's simplicity[0], but
there is the transpose method from Math::Matrix[1] which should do it e.g
shell> perl -MData::Dumper -MMath::Matrix -e 'print Dumper(
Math::Matrix->new([1..3],[5..7])->transpose )'
$VAR1 = bless( [
[
1,
5
],
[
2,
6
],
[
3,
7
]
], 'Math::Matrix' );
Which is more or less like mapcar, minus the blessing.
[0] there is a mapcar method in the LISP module, but that's a horror show
of a module
