( [id://3333]=superdoc: print w/replies, xml ) Need Help??

I am trying to figure out if what I am trying to do is possible, obvious (to people != /me) or just "not the Perl way". Here's the way the I wanted to define a sub:

sub functionname($string_param, @array_param, $other_string_param) { # do something with parameters, return values }
I got this structure from doing things in JavaScript or Python, but it makes sense to me - more sense than calling on anonymous bits of @_. I've looked at prototypes, but those don't (a) make sense to me and (b) don't seem to be quite what I am looking for.

I want to do this because I want to have warnings thrown up when a sub is called with the wrong kind of input, and I want sensible parameter names in my sub blocks. This may be at odds with the "arbitrarily large flattened list" parameter structure that they talk about in the Camel book.

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