What you don't understand is that perl compiles that sub foo and compiles the lexical-ness of the my declarations before it executes the foo() and before it sets those lexicals below the function call.

I think it's clearer like this. It's nearly the same thing, but it doesn't have the lexical masking that yours has. That just confuses the issue.

use strict;
use warnings;

foo();
my ($foo, $berries) = (1,2);
foo();

sub foo {
    print "$foo, $berries\n";
}

Here you can clearly see I'm using the foo and berries declared lexically after the function is called. The declaration happens at compile time and the initialization happens at runtime.

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).
Want more info? How to link or How to display code and escape characters are good places to start.
