What is the easiest way to push a scalar variable containing text into
an array?
i.e.
$text = 'here is
a line
that has
four lines';
@lines = ???
the end result is:
@lines =('here is', 'a line', 'that has', 'four lines');

push @lines, split /\n/, $text;
Or if didn't really want to push by rather assign:
my @lines=split /\n/, $text;

So close! If only you had asked ' ... to split a scalar variable ...'.
Then you would have asked a "self-answering question" (SAQ).

@lines = split(/\n/,$text);

That is a SAQ: perldoc -f push

But this has nothing to do with pushing a single scalar into an array as you
asked for at the beginning.
Just split// the text at newline and then push() or splice() the new
elements into the array. Or you could use an array slice instead, too.
