I had considered not using eval, but in this case I could see no practical advantage to the alternatives – and eval was more consistent with my goal of simplicity. For non-trivial uses, however, I agree that eval's costs (e.g., quoting clutter, parsing overhead, and security concerns) almost always outweigh its benefits.

Still, if you think there is something inherently evil about eval that ought to eliminate it from all consideration, I would be interested in hearing your reasoning.

Thanks for your comment.

Cheers,
Tom

• 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.
