One other thing: note that even the most strongly typed langauge will let you define a function that takes one type and returns another:

$ ocaml Objective Caml version 3.08.1 # let rec sum = function [] -> 0 | i :: l -> i + sum l;; val sum : int list -> int = <fun> # let list = 1 :: 2 :: 3 :: [];; val list : int list = [1; 2; 3] # sum list;; - : int = 6

(If you're not familer with OCaml, the above makes a function that takes a list of integers and sums them, returning a single integer. In OCaml, "int list" and "int" are totally seperate types.)

Indeed, a language that didn't allow you to do this would be very limited. All Many of the examples you presented essentially do this, although the actual function call is hidden away by Perl.

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.
