No, you are using /g in list context which swallows the whole file now and returns a flat list.

You need an external loop to process the 3 groups

update

With a post while you can have the loop in the same line

 push @res, [ $1,$2,$3 ] while m/.../g

In the OP you were originally looping with $_ , that's confusing.

you should rather be concerned about maintainability than shortness.
