Here is a simpler approach, if you can use Inline::C: #!/usr/bin/perl -w
use strict;
use Inline C => q{ int evalseq() { return PL_evalseq; }};
for (1 .. 10) {
eval q{ print "in eval (", evalseq(), ")\n" };
print "outside eval (", evalseq(), ")\n";
}
Of course this delves into undocumented internals, so no guarantee that it will work with every past and future version of perl. (It may also need a pTHX or something for threaded builds, but I don't have one handy to check.)

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).
