When you're looking for something in particular, it's easy to just look for
that specific thing. As you say, Perl has different definitions of what
"\n" actually translates to depending on platform and context. So rather
than worry about "\n" just have Perl look for what you're actually lo

The pipe | operator isn't single characters only:
$string =~ /this|that|the other/;
But the character set is:
$string =~ /[abc]/; # matches any a, b or c
$string =~ /[tw]hat/; # matches 'that' or 'what'
What you're looking for is something like this:
$string =~ /\\L(ength)?\b/;

Right, so $project{$projectno} is an ARRAYREF, and each entry pushed in
this way will be a HASHREF.

But just in case you're on *nix and processing a Windo~1 file, split(
/[\r\n]+/, $msg ) is reasonably bullet-proof for breaking a string
How about something like this:
next unless m:(\d\d\d\d)/(\d\d)/(\d\d):;
$start_date = "$1$2$3";

Or if you want the characters themselves:
@result = map { chr( hex ) } @source;
Or as a solid string:
$s = join '', map { chr( hex ) } @source;

Dude! This one is really easy:
print hex("ff"); # 255!
so @result = map{ hex } @source;

Here's my take:
print 'it\'s time \\ to go';
The backslash can quote the single-quote, and hence another backslash as
