I am interested to learn the fastest and shortest way to convert a
textfile-like string to an array and back again (chopping newlines).
Test program follows. Improvements (golf or speed) welcome.
/-\
use strict;
my $x = 'FLAMING_OSTRICHES';
This is first test line
This is 2nd
And 3rd

my @lines = split m[\Q$/], $x, -1;

I'll prolly say something stupid here, but:
my @lines = split \n, $x;
Joy,

Not tested, but I would guess that the obvious
@lines = split /\n/, $x, -1; pop @lines;
might be both fastest and

$/ can be different from \n though.
And popping the last field is dangerous - you don't know if
the file ends with a newline. Also, you now have no chance
to reconstruct the exact equivalent

Yes, but his example data was text in a here document.
But you can always do
split m,$/, $x, -1;

split m,$/, $x, -1;
In bizarre cases, $/ might contain regex metacharacters.
Don't forget the \Q.

Sorry, I thought (and still do) that the OP's caveat was
understood to still be in effect.
join \n, @lines, $tail;

chomp(my $tmp=$x); my @lines=split /\n/,$tmp,-1
Very nice.
