I belive the real source of the problem is the lack of non-alphanumeric symbols in ASCII. We all know Wall was pretty meticulous picking right symbols. So how on earth did he arrive at "." for concatenation? As you say, "." is pretty universal for "stop". Personally, I think "." and "->" both suck for different reasons. It's a choice between a lesser of two evils and there ain't much you can do about it.

• 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).
