Actually, this bug isn't really related to the ternary operator. The bug is with using array derefencing on an array rather than a reference to an array.
perl -e '@{ $_; @_ } = 1'
Bizarre copy of ARRAY in leave at - line 1.
Note that this code:
perl -e '@{ @_ } = 1'
does not produce the error. However, it does produce the error when run in the debugger.
I expect it's something to do with the state of the stack after the contents of @{ } are evaluated. I can't explain why it works in some cases (even though it shouldn't) and not in others. :)

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).
