... the issue is the way doublequotes are interpolated.
No, per tye above, the problem is with scoping within a statement:
c:\@Work\Perl\monks>perl -wMstrict -le
"my %foo = qw(do done eggs ham was were);
;;
my @v;
(@v = keys %foo) == 1 or warn qq{Got more than one: @v};
print qq{V:@v};
"
Got more than one: eggs was do at -e line 1.
V:eggs was do

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).
