<at> is really "@". I saw it too in MJD's-mail. It is probably an artefact of not being able to use "@" in some mail messages

my  @rows = split /\n/, $_;

Split what is found in the magic variable $_ on linefeed into the array @rows.

my $x = pop  @rows;

"pop" the top element of the array @rows into scalar variable $x

is(scalar( @$result), $n_courses, "test $.: one room per course");

"is" is a function in the Test::More module (to build an automated test suite). It checks if the value of scalar( @$result) is equal to $n_courses.
