I often use one of the following constructs for my private methods. Both have their benefits (the first gives a compile error, the second one dies during runtime but is easier to read). However, I wonder if there are other, better ways?
# private method add
my $add = sub {
my $self = shift;
my $amount = shift;
$self->balance($self->balance+$amount);
};
or
# private method padd
sub padd {
my $self = shift;
my $amount = shift;
caller(0) eq __PACKAGE__ || die "private method";
print caller(0) . " " . __PACKAGE__;
$self->balance($self->balance+$amount);
}

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).
