To reuse getCreditAccounts(), you'd have to first rewrite the method to return array ref, and not a copy of the array you are attempting to ultimately change.
# private getCreditAccounts
sub getCreditAccounts {
caller(0) eq __PACKAGE__ || confess "getCreditAccounts is private"
+;
my $closure = shift;
my @accounts = @{ &{$closure}( "CREDITACCOUNTS" ) };
return @accounts;
}
# working on a copy of the original array...
my @anotherArray = $obj->getCreditAccounts();
push @anotherArray, "Data";
From there, you could possibly do something like
# private getCreditAccounts
# now returning reference to the original array
sub getCreditAccounts {
caller(0) eq __PACKAGE__ || confess "getCreditAccounts is private"
+;
my $closure = shift;
return &{$closure}( "CREDITACCOUNTS" ) };
}
# public to add accounts to the creditaccounts
sub addCreditAccount {
my $closure = shift;
my $account = shift;
push @{ $closure->getCreditAccounts() }, $account;
}

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).
