Careful before saying that no such facility exists in
Exporter. There are, in fact, at least 3 ways to do this
while using Exporter.
- Use the export_to_level method.
- Do like Carp does and have flags listed in
@EXPORT_FAIL and processed in an export_fail function.
- Write a custom import that looks like this:
sub import {
my $self = shift;
my @out;
foreach (@_) {
if (ref($_)) {
# Do one thing
}
else {
push @out, $_;
}
}
@_ = ($self, @out);
goto &Exporter::import;
}
UPDATE
Two quick notes. First of all I had put the case of
Exporter wrong. Oops. Secondly the point here is that
you can preprocess the list of arguments being imported
in any way you please before Exporter sees them. (eg Take
references out of the list and do something useful with
them.)

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).
