( [id://3333]=superdoc: print w/replies, xml ) Need Help??

I've been thinking a bit lately about the language features that I find indispensible: that is, if I'm hacking about in a language that doesn't have one of these, I either implement it right away, if possible, or miss it terribly and grumble about its absence.

My "must-have" feature list is, in part:

If I spend much more time playing around with Haskell, I'll probably want to add argument pattern-matching, lazy evaluation (Update 2004/07/01: including non-strictness, of course), and currying to that list.

It's interesting (although not too surprising) to me that my list of must-have features has changed so much in the past few years: back then, I'd probably have listed such low-level arcana as predictable memory layouts and pointer arithmetic. Back then, though, I was doing a lot of bare-metal C hacking; these days, I'm much more interested in functional programming.

It's admirable that Perl gives me what I want, and usually with at most as much fuss as any other language would (although sub {...} for lambdas is a bit verbose).

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.
