> 2. I'm not sure I understand how a function can be thought of as a second-class citizen;

because that's FUD

"First class object" aka citizen basically means you can pass functions around as arguments to other functions. E.G. most BASIC dialects I've seen couldn't do that.

It's a necessity for functional programming...

Perl is actually better in functional programming, since Python is restricting lambdas to one expressions only, while anonymous subs are free.

And Python doesn't offer any block prototype to make it even easier like sub foo (&) { $code = shift; ... }

Superficial people will claim that the need to explicitly reference named subs in Perl with ...

\&foo

means they are not first class.

Superficially so because almost everything in Python is implicitly a reference.

Now, who said explicit is better than implicit again ...???

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.
