Having had a further look at your OP, you seem to be complaining that the scalar ref value should readonly - I was thinking that you were wanting the anonymous array to readonly?
So is the following a correct summary of your position as to how you would like things to work?
[ 1, 2, 3]; # a readonly temporary reference to a mutable anonymous a
+rray
[ 1, 2, $x]; # also a readonly temporary reference to a mutable anonym
+ous array
bless 'Foo', [1,2,3];# a readonly temporary reference to a mutable ano
+nymous array
# where the array was mutated by blessing it
$a = [1, 2, 3]; # $a is a rw copy of the temp ro array reference

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).
