Cheers to skeeve and thinker. Still doesn't look very obvious to me, but it does the job.

I would add

perldoc perldsc

And it happens that the free online chapter from merlyn's new book Learning Perl Objects, References and Modules covers this very topic. Check it out on the O'Reilly website.

NB: that shouldn't stop you from buying the book :-)

An "array of arrays" is in fact an array of references to arrays. So each element of your @M is an array reference leading us to:

foreach $aref (@M) {...

To get the actual array from an array reference, one usually writes @$aref leading us to

    foreach $element (@$aref) {...

and that's all about it.
