Wow! What a great response. Thank you all for the insights!!
Am much closer to the goal, now just stuck on the "inverse, sort of" (from the Camel Book) of "use", "no". Sorry, not meaning to be cryptic. Instead, here's some code that demonstrates what I was hoping to achieve:
use strict;
my $debug;
BEGIN { $debug = 3; }
use if ($debug > 0), 'warnings';
use if ($debug > 1), 'diagnostics';
if ($debug > 2) { no warnings 'redefine'; }
run_sub();
sub run_sub { print "Running\n";}
sub run_sub { print "Ran\n";}
if ($debug > 3) {print "DEBUG: blah, blah, ...\n";}
Have tried a few modifications, but none eliminated the 'redefine' warnings when ($debug > 2).

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).
