in reply to A better (ie.more concise) way to write this?

Now the dust has settled on this one, I have a question ... yes, a question ...

My solution to this problem came up more-or-less like this:

perl -e 'use strict; use warnings; my @a = ( 1..10 ); foreach (@a) { $_ = ( $_ + 1 ) % 10; }; use Data::Dumper; print Data::Dumper->Dump([\@a], ["a"]);' $a = [ 2, 3, 4, 5, 6, 7, 8, 9, 0, 1 ];

In other words, using the foreach() construct to iterate through the list/array, with $_ being an automatic alias to each entry in succession, rather than actually indexing into the array.   Intuitively, this seems to me that this would be “more efficient.”   Is it?

Also... among the various solutions that were proffered in this thread, how much difference in timing are we actually talking about here?
