If you are really going to 'globally expose'(¹) utility functions this way, then you should at least give some thought to the names, and get_id() is just about as bad as it gets.

(¹) Which seems to be your intention, though as halley pointed out the definition of global is somewhat limited.

What id is that? A file identifer? A personnel identifier? A user identifier? A group identifier? A rabbit identifier? Is Idaho up for sale? Your program is a step in your quest for world-domination and your starting with Indonesia?

Or maybe the problem you are solving needs a little Freudian help, and some impulsive behaviour?

And is that get a new one? The old one? The only one? The current one? The next one?

Once you have addressed those questions, your likely to end up with a sub called retreive_current_effective_user_id_for_this_process();, but then that would probably be more easlily written as Process::Current::user_id(); (season with get/put, or get/set to taste).

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.
