[OT] Apple introduces Swift as Objective-C sucessor

My experience in ObjectPascal tells me that this limited loss of 
performance is quite acceptable when you debug the code or in 
routines that don't need the max performance. So it's similar to 
D array bound checks. In some functions (like the @safe ones in 
D) you can even decide to keep it on. So I like checked 
arithmetic by default if there are ways to disable suck checks in 
specific functions/parts.


The good Graydon (one of the main designers of Rust) has written 
some quick notes on Swift:

Currently Reddit-Programming is buzzing a lot about Swift.
