LLVM 3.1 released

Collections subscripting operator [] and boxed C strings are life-savers. Instantiating obj-c object is always a pain cause the syntax is very verbose, expecially for NSString:

  NSString *s = [NSString stringWithCString:"hello" encoding:NSUTF8StringEncoding];
  NSString *s = @("hello");

it's 11 characters vs 67. Now what I really, really miss is the implementation of the NSString concatenation operator. stringWithFormat isn't always the answer nor appendString. Please forgive me if you find that my idea is silly:

  // String concatenation
  NSString *s = @+(@"hello ", @"world");

Or maybe some concise dictionary operators.

  NSDictionary *d1 = @{ @"first":@"Hello", @("second"):@"World" };
  NSDictionary *d2 = @{ @"third":@"Greetings" };
  
  NSDictionary *cd = @|(d1, d2); // Dictionary merge
  NSDictionary *id = @&(d1, d2); // Dictionary intersect
  NSDictionary *dd = @^(d1, d2); // Dictionary difference

Sweet, especially the Objective-C Literals: http://clang.llvm.org/docs/ObjectiveCLiterals.html

Oh cool! I didn't know Julia was LLVM backed! Now if only it had a good IDE package.

Looking forward to playing with autovectorization in ruby-llvm. https://github.com/jvoorhis/ruby-llvm

A cool, seems to include the changes that were needed by llgo: https://github.com/axw/llgo

Is there any successful language/runtime that runs primarily on LLVM?
