OK, I think I understand most of those examples.

Except foo($#a) has me scratching my head. It's marked modifiable, but it's not a reference (at least not obvious to me). Maybe this is the older, darker magic of the aliasing involved with @_ in subs? (Personally, I avoid coding in such an implicit way, preferring to catch the passed arguments explicitly.)

I went back an read most of the thread, and, while much of the discussion was over my head, it seems that those in the know are trying to fix it appropriately (or have already done so).

Thanks to all for a mind-expanding discussion.

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.
