"I strictly reserve map for coercion of a set of FOO items into a set of BAR items (@lista -> map -> @listb)..."

And i don't understand why you insist on this.

Just because there must be an example:

#!/usr/bin/env perl
use strict;
use warnings;
use Data::Dump;

my @foo = ( 1 .. 10 );
dd \@foo;
my @bar = map { ++$_ } @foo;
dd \@foo;
dd \@bar;

[download]

So why is map { ++$_ } @foo; wrong?

I vaguely remember that there where some performance issues...patched?
