So I've been looking at the Dart language specification recently published by Google (draft version 0.01). So far, I'm not really enthusiastic. Here's my reading notes.
Class-based OO and Interfaces
At first glance Dart code looks like Java (and nothing's wrong with that, I'm not going to criticize a language based on my idiomatic preferences). The syntax is very similar, with the dot to invoke methods, the curly braces for blocks, the required semicolon to terminate statements, the main() function, the general feeling of verbosity. The familiar classes and interfaces are…
Safe.pm, originally released with perl 5.002, has been an experiment to bring compile-time safety to perl. It allows to compile a (usually user-provided) snippet of perl code and execute it, while forbidding a configurable list of operations -- for example, all perl built-ins that would require disk or operating system access. Moreover, Safe "chroots" perl's main:: namespace, so the real program's variables can't be overwritten by the ones created by the code executed from Safe.
It's pretty clear that Safe does not provide absolute safety. For once, even overly restricted, it can be a…
On all released 5.10.* versions of Perl to date, the smart match operator can segfault if passed recursive data structures (like arrays that contain a reference to themselves).
I fixed that. The
fix was pretty trivial: basically, the C code in the implementation of smart match was creating two hashes, called
seen_this and
seen_other; however, a typo made it so only
seen_this was actually created. Segfaults ensued if the code was trying to use
seen_other.

I can haz Perl.
