Conceptually I understand how this could be done, but I have two problems with this proposed solution. In my full application, the actual functions being executed are not even defined in the same script. They get pulled in via a do() call to another script. It would be a maintenance headache to maintain a dispatch table in this script. It's much easier to simply get the function name and execute it as a function ref.

The second problem is more practical. The prototypes of functions that get called are all different. Some have no args, some have one scalar, others have multiple array refs, etc. How could I set up a generic JSON message to convey such a varying list of parameters?

• 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).
