It may be that local doesn't do what you think it does. It would make a lot more sense to write something like this:
package blarg;
use strict;
use warnings;
sub hrmph {
our $global = "blarg";
print "$global\n";
local $global;
$global = "hrm, just in here!";
print "$global\n";
# when this scope is done, global goes back to "blarg" automatical
+ly
}
Note that use vars is pretty much the same thing as our except that the package variable isn't bound locally to a sub as a pseudo-lexical. But if it was a case of use vars local would work the same way. It doesn't make the variable lexical, it makes the values you use in it local to the scope.

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).
