I've been reading this and realised that new is not a keyword in Perl!

Correct! Though it's generally considered polite to pay for those books than to read the pirated versions online (you may want to remove the link and replace it with a reference to the actual book).

Are these the accepted way to do it? Can they be imporved?

Yes, those are (syntactically) correct and best practice. They can be improved in the ways you showed:

Is it OK to condense that down to this and avoid the intermediate variable definition?

Yes, if you don't need the object - though some OO classes make a habit of returning the original object from some methods in order to explicitly allow method chaining, e.g. my $json = JSON::PP->new->ascii->pretty->allow_nonref;

Are the brackets necessary

No, they're not; IMHO it's fine to leave them off when there are no arguments (others might feel differently).

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.
