Hi Beech,
> # goto &CORE::hex; ## FAIL
I can't reproduce any problems with goto &SUB here.
Neither with hex nor with sleep .
How does it "fail" for you?
update
use strict;
use warnings;
warn "Version $]";
warn "Prototype", prototype "CORE::sleep";
my $sleepcounter;
BEGIN {
*CORE::GLOBAL::sleep = sub {
warn "start wrapper ($_[0])";
$sleepcounter += int $_[0];
goto &CORE::sleep;
};
}
warn "return: ", sleep 2.3;
warn "total sleep( $sleepcounter )";
Version 5.016003 at d:/Users/lanx/pm/core_sleep.pl line 4.
Prototype;$ at d:/Users/lanx/pm/core_sleep.pl line 5.
start wrapper (2.3) at d:/Users/lanx/pm/core_sleep.pl line 15.
return: 2 at d:/Users/lanx/pm/core_sleep.pl line 23.
total sleep( 2 ) at d:/Users/lanx/pm/core_sleep.pl line 25.

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.
