So the sub "returns the array" (whatever that means) then values from the stack are copied into a list and then for() aliases them? That's a lot of extra steps you have invented. In reality (if anybody cares), the sub pushes onto the stack (copies of the scalar values from the array) and the for() iterates over what is on the stack (just using them in-place).
Maybe you'll then try to explain why "return (@a)" behaves differently than "return (@a, 'b')" and differently
than "return ('b', @a)" when assigned to scalar? According to your explanation, everything is flattened to the list, and then the assignment to scalar should always pick up the last element from the list. But it does not.

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).
