It's been a tried and true method of most of the CIS classes that I took (and the one that I taught). Your profs aren't asking you to write an implementation of a linked list because they're hoping that their undergrads are going to discover some breakthrough in the application of the language, after all.

I daresay though that Perl might not be the place for you to start, depending on what you want to learn. Like you, I started out in C, stuck with it a bit, and then moved on to Java before I started to touch Perl, Python, PHP, &c. It provides you with a solid foundation in the way memory management works, and if nothing else will lead you to respect what Perl and its cousins can do more.

So by all means, reinvent the wheel when you have the luxury of doing so. It's a great way to learn the trade. The principle of NOT reinventing the wheel applies mostly when you're more concerned with *getting* something to work than with understanding the process of how it works.

Cheers!

• 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.
