There is no such general function. And that's because there's no general way of creating an object. See, unlike normal languages, in Perl you have to do everything yourself when creating objects (which is very non-Perl). Some people use hashrefs or arrayrefs for their objects, and stuff all the attributes in the things the references point to (and those same people will vote '++' for if someone posts a coding guideline saying "Don't use global variables"). The advantage is that you can access the attributes all the time, from everywhere - the same advance as putting all your variables in main:: gives you.

But people preferring lexical variables over global variables; who think that encapsulation is a good thing, who simply think that variables should be appropriately scoped, or that it's nice to be able to inherit a class without having to peek inside it to do it properly, will hide the attributes, making them unaccessable from the outside.

So, no, you cannot do so.

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.
