It is only applied to the "last statement of a subroutine". Not to the last statement of a do block?
The line you read may only have been talking about the last statement of a subroutine, but it applies for the last statement do blocks and everywhere else a return value is needed from a loop. You've even demonstrated this yourself.
But suddenly, you read a bit of the documentation, apply it to the wrong circumstance, assume that your misinterpretation is the only interpretation.
Actually, you're the one who is being a slave to the documentation, not listening to anything else.
And I'm pretty damn confident that I could find numerous examples of you using, and recommending the use, of the return value from a block.
Straw man. It's the return value of loops that's not defined, not blocks. eval and do aren't loops.

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).
