Hi fabalicious

As an aside, and this is merely a matter of style, your method of doing what you want to do is very verbose.

I would choose to write it as

print "@$_\n" for @M;
[download]

taking advantages of some of some not so intuitive Perl idioms, like using @$_ to dereference each array, and the fact that "@array" will join the elements of @array with $", which is a space by default. And it saves you printing an extra space character at the end of each line :-)

In the spirit of TMTOWTDI
