From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Pointers are not guaranteed to be safe. DIP1000 was supposed to solve the issue of a pointer referencing to a now expired variable (see example below), but it's being replaced by something else instead.

int* p;
{
  int q = 42;
  p = &q;
}
writeln(*p);     //ERROR: This will cause memory leakage, due to q no longer existing

So I guess they are forbidden in @safe mode?

but it's being replaced by something else instead

Do you know what is the replacement? I tried looking up DIP1000 but it only says "superceded" without mentioning by what.

This makes me wonder how ready D is for someone that wants to extensively use @safe though.

This XML parser of mine uses safe by default.

It also seems to require a GC though...

newxml is GC only, for simplicity sake.
