I am very unsure as to your question and the intent of your code?
I share your uncertainty. I think perl-diddler may have invented yet another way to write spaghetti code without using goto. A dispatch table approach such as you exemplify tends to be my knee-jerk approach to the sort of problem that I imagiine gave rise to the OP.
# local can only "mask" an "our" or a global variable ...
...
# A "my" variable cannot be "localized"
I tend to think of this a bit differently. My conception is that a my variable can be completely "localized" or isolated within a scope, whereas an our (or package global) variable cannot. The potential scoped isolation of lexical variables makes it very easy to reason about them, a great advantage.
c:\@Work\Perl>perl -wMstrict -le
"our $xyzzy = 33;
print qq{A: $xyzzy};
{
local $xyzzy = 55;
print qq{B: $xyzzy};
zot();
print qq{C: $xyzzy};
}
print qq{D: $xyzzy};
;;
sub zot { $xyzzy = 99; }
"
A: 33
B: 55
C: 99
D: 33
c:\@Work\Perl>perl -wMstrict -le
"my $xyzzy = 33;
print qq{A: $xyzzy};
{
my $xyzzy = 55;
print qq{B: $xyzzy};
zot();
print qq{C: $xyzzy};
zonk();
print qq{D: $xyzzy};
}
print qq{E: $xyzzy};
;;
sub zot { $xyzzy = 99; }
;;
sub zonk { my $xyzzy = 9999; }
"
A: 33
B: 55
C: 55
D: 55
E: 99
Update: But then there's PadWalker... (sigh)

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).
