Maybe something like this (if I'm understanding you correctly):
package Bar;
use Exporter 'import';
our @EXPORT_OK = qw(x);
sub x {
print "x(): @_\n";
}
1;
package Foo;
sub import {
print "Foo::import(): @_\n"; # debug
require Bar;
# do whatever you want with the import() args, e.g.
shift @_;
Bar->import(@_);
}
1;
#!/usr/bin/perl
use Foo 'x'; # x() will be imported from Bar into Foo namespace
# (as would be done when using a hardcoded "use Bar 'x'
+" within Foo)
Foo::x('bla');
__END__
$ ./824136.pl
Foo::import(): Foo x
x(): bla

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).

or How to display code and escape characters
are good places to start.
