Yeah, that's right. I'm back, and I have something to say. This is really a reply to people who've given code examples in this thread.

I don't understand the last line of:

sub account_over_limit {
    my ($account, $balance) = @_;
    return exists $LIMITED_ACCOUNTS{$account} && $balance > $LIMIT;
}

And I don't understand the point of:

BEGIN {
   my $var;
   sub set_var {
     $var = shift;
   }
   sub var {
     $var;
   }
}

I've had numerous problems trying to determine where a global was changed, and I have a feeling there's a good anti-global argument around here somewhere, but I can't find it. When a script is doing alot of calculating and outputting just the end result, I don't think it matters how localized things are. You still won't know what affected the output.

Another, barely related thing--I'm just about done with a GNU tar GUI for Windows, and I'm finding good uses for goto all over the place.

Anyway, please make your code examples as simple as possible and explain them properly.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
