Suppose warn.pm is
# warn.pm
package CORE::GLOBAL;
use strict;
use warnings;
use subs 'warn';
sub warn {
print "WARN '@_'!\n";
CORE::warn @_;
}; # die:
1;
and warn.pl is
# warn.pl
#!/usr/bin/perl
use strict;
use warnings;
warn 'first warn';
use warn;
warn "second warn";
Then executing warn.pl produces
first warn at warn.pl line 6.
WARN 'second warn'!
second warn at warn.pm line 9.
Why doesn't the first warn (the warn prior to the "use warn;") utilize the CORE::GLOBAL::warn? Why in this case does the location of the "use warn;" matter?

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).
