> lexicals declared at file-scope are global variables

No, it's a different quality if a variable can be accessed and altered in a different file from another author.

Furthermore putting a file scoped lexical behind the last sub would protect it from becoming closed over.

Package vars are accessible nonetheless, no matter where you define them.

perlglossary even makes a distinction between package vars and special vars.

In Perl, only certain special variables are truly global—most variables (and all subroutines) exist only in the current package.

Are you posting in the right place? Check out Where do I post X? to know for sure.
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.
