( #3333=superdoc: print w/replies, xml ) Need Help??

Can you remember:

  • where split() in void context puts the results?
  • what $| = 2; print $|; will output?
  • what weak references are, and why you might need them?
  • how to use formats?
  • what all of the default punctuation variables do?

These are just things I thought of off the top of my head. I know the answers to these (except the last two), but I bet another very experianced Perl coder would have to look it up (and some of this stuff is in very obscure places). They'd come up with a completely different list that would stump me. In other words, we would each know a some details that the other doesn't.

(Unless, that is, your name is Abigail. He can probably beat Larry.)

Neither of us would a truely complete understanding of the language. We'd just know a useful subset which has been grown over time by our individual experiances with the language.

In their orginal forms, C and LISP are minimalist languages (I find LISP surprisingly so). If they display complex behavior, it's because they use combinational explosion to produce it (i.e., combining individual components on a massive scale). Perl does do combinational explosion, but it gets a lot of power by refining the details of individual components.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • 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.
