• Commented on C Programming: What is the difference between an array and a pointer?
  Well, that's because (with the exception of VLAs in C99) sizeof is purely a compile time operation. It only looks at the types: sizeof EXPR == sizeof (typeof(EXPR)) (if we pretend C had typeof for a moment)....
• Commented on C Programming: What is the difference between an array and a pointer?
  Note that there's an interesting parallel between C and Perl when it comes to arrays. Neither C nor Perl have array values (that is, values that represent arrays). When you evaluate an array in C, you get a pointer to...

  Why is a raven like a writing-desk? (Lewis Carroll)

  This is a copy of an article I wrote a long time ago. I'm putting it here to give it a more permanent home. Sorry for being off topic again!

  I don't quite agree. OK, there's the "doesn't "enable" shit" comment early on, but that was directly followed by a list of concrete questions I had after seeing the documentation. But the funny part is that the answer given by...

• Posted Two RegExp bugs in Internet Explorer 8 to mauke

  It turns out there are at least two bugs in IE 8's Javascript regex engine. One of them is widely known, the other one doesn't seem to be.

  Testcase: /^(?:(?=(.))a|(?=(.))b|(?=(.))c)/.exec('bar')
  Correct result: ['b', undefin…

• Posted No semicolon after return values to mauke

  Perl lets you omit semicolons at the end of a block. That is, you can treat ;

• Aristotle commented on Why you probably don't want to use claws-mail

  Again, it sounds like design-by-programmer. I don’t disagree with your complaints.

  The thing is, the people who wrote a program or have been using it for a long time, no matter how inept its design, will always believe it is quite obvious and easy to use. If you barge in there with a barrage of questions, it’s liable to make you look dumb to them. It doesn’t mean you are dumb, but from their perspective it looks that way. And then the slightest show of annoyance or general attitude will invariably look like a show of entitlement of some sort.

  That’s not how i…

• Olivier Mengué (dolmen) commented on C Programming: What is the difference between an array and a pointer?

  You should put more emphasis on sizeof for pointers: the pointer has no idea of how many elements it points to.

  int array[5];
  int *ptr = array;
  printf("%zd\n", sizeof(array)); // 5*sizeof(int)
  printf("%zd\n", sizeof(ptr));   // sizeof(int*)
  printf("%zd\n", sizeof(*ptr));  // sizeof(int)

  p5-mop (planned for Perl core in some future version, perhaps 5.20; currently on GitHub, but not on CPAN yet) seems to fit your description.

  Here's some documentation on the syntax.
