Why does the "no warnings 'uninitialized';" not work?
"use warnings" and "no warnings" are lexical, which means that you can't change them in modules you use. I'd remove "use warnings;" from Tokenizer.pm, or add
BEGIN { $INC{"warnings.pm"}="blah" }
to the beginning of your program.
EDIT: To explain, %INC is a hash table where Perl keeps track of what modules it has already loaded. The above line tells Perl "yeah, yeah, I've already loaded "warnings.pm". "warnings.pm" does its work in warnings::import(), called when some code does "use warnings," but since you've told it that "warnings.pm" has already been read, and warnings::import() is undefined, Perl won't call it, and hence won't create the annoyance.

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).
