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

One of the reasons O'Reilly books can't charme is are the poor indices . . .

Perhap. I'm comparing the Camel's index with the multitude of "Learning Perl for Fools" books out there, where they basically slap an index with a few common terms and leave the rest to the poor sod that bought the book.

What I also don't understand is that you wouldn't buy certain classes of books, because they are easily outdated, yet you break a lance for the Camel.

How much fundamental of the Camel was really obsoleted by 5.6.* or 5.8.*? Declaring variables is still the same. Looping and conditionals are the same. Declaring subroutines is the same, with at best a few attributes being added, if anything. Builtins are pretty much the same, with a few details being different. Complex datastructures, packages/modules, and OO programming are the same (notwithstanding meryln's complaints about ref $class || $class;, or the various other object systems you can use under Perl). Trying to output native, optimized code from your Perl code is still a tricky proposition. Tied filehandles became useable in 5.6.0 (IIRC), but that's a fairly small portion of the book, and it covers them anyway. Threading became somewhat useable in 5.8.0, but again, it's a small part of the book.

So small, specific sections might be a bit out of date, but I don't forsee it being unuseable at least until Perl6. That's a long ways off and a lot of Perl5 stuff will still be applicable by then. Probably Perl4, too.

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.

Title:
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 or How to display code and escape characters are good places to start.
