You're right, the post-interpolated line should read:
*main::scott = "scot2";
Here's what I've been using to test my assumptions:
#!/usr/bin/perl
$test1 = "value of test1";
$test2 = "test1";
$test3 = "Why are you here?";
# refers to *main::test1
print "=>$main::{$test2}<=\n";
print "Original \$test1: ...$test1...\n";
$main::{$test2} = "test3";
# $main::{"test1"} = "test1";
print "\$test1 = >>", $test1, "<<\n";
print "Main package: ", $main::test1, "\n";
As you can see, $main::{$test2} evaluates to a typeglob.
Saying that $main::{$test2} = "test3" changes the scalar is technically incorrect. (Though it is what my previous answer would lead one to believe!)
Dunno where that u came from. Maybe it's a mu?

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).
