The last task, to match a question, can be solved quite easily by reversing the string.
my ($m) = reverse($myvar) =~ /"\?(.*?)"/s;
$m = reverse $m;
print "matched <$m>\n";
Note that it's OK to use .*? here. And due to optimizations in the regex engine it's even faster to use it than a negative char class, if the following pattern is constant as it is in this case.
It's also very easy to make it work for escaped quotes by adding a negative look-ahead.
my ($m) = reverse($myvar) =~ /"\?(.*?)"(?!\\)/s;
Note that here you must use .*? instead of a negative char class since you want the engine to backtrack.

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).
