( #3333=superdoc: print w/replies, xml ) Need Help??

$result = function(@args) would be usual syntax. You almost never need &. The main effects of & are that it passes @_ to the called function and you don't need () after the function name to pass strict. However do note that &::function and ::function are calling main::function(). This matters if you are in another package:

#package main; # this is implicit bar( qw( some args that were passed along ) ); foo( 'foo() stuff' ); ::foo( '::foo() stuff' ); &::foo( '&::foo() stuff' ); sub bar { &foo; } sub foo { print __PACKAGE__, " foo got '@_'\n" } foo; # bareword will work with no strictures after sub defn package Foo; foo( 'foo() stuff' ); ::foo( '::foo() stuff' ); &::foo( '&::foo() stuff' ); sub foo { print __PACKAGE__, " foo got '@_'\n" } __DATA__ main foo got 'some args that were passed along' main foo got 'foo() stuff' main foo got '::foo() stuff' main foo got '&::foo() stuff' main foo got '' Foo foo got 'foo() stuff' main foo got '::foo() stuff' main foo got '&::foo() stuff'

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