Yes, you're right. My reply was a bit tongue-in-cheek - the OP asked why his grep aliasing example "didn't work" and I resolved to beat it into submission ;)

There's a slight difference though. *m = \@l; aliases the entire array object. The sub {\@_} trick creates a new array object containing scalar elements which are aliased to memberes in @l matching /a/ (in OP's example it contains only one element aliased to the first element in @l - "a").
