The Next Big Languageの正体は？

Steve Yeggeが期待する言語があるらしい。ただ、名指しをせず、特徴だけ記してある。(知っている人は知ってるかもと言っているから、まるっきりの新言語ではない)
特徴。

  • NBL does not replace C++
  • NBL is garbage collected.
  • NBL isn't about winning beauty contests
  • Rule #1: C-like syntax
  • Rule #2: Dynamic typing with optional static types.
  • Rule #3: Performance
  • Rule #4: Tools
  • Rule #5: Kitchen Sink
    • Object-literal syntax for arrays and hashes
    • Array slicing and other intelligent collection operators
    • Perl 5 compatible regular expression literals
    • Destructuring bind (e.g. x, y = returnTwoValues())
    • Function literals and first-class, non-broken closures
    • Standard OOP with classes, instances, interfaces, polymorphism, etc.
    • Visibility quantifiers (public/private/protected)
    • Iterators and generators
    • List comprehensions
    • Namespaces and packages
    • Cross-platform GUI
    • Operator overloading
    • Keyword and rest parameters
    • First-class parser and AST support
    • Static typing and duck typing
    • Type expressions and statically checkable semantics
    • Solid string and collection libraries
    • Strings and streams act like collections

Additionally, NBL will have first-class continuations and call/cc. I hear it may even (eventually) have a hygienic macro system, although not in any near-term release.

  • Rule 6: Multi-Platform

NBL will run, at a minimum, both standalone and on the JVM. I'm not sure about plans for .NET, but it seems like that will have to happen as well.

これで全部かな？ 大きな手がかりはcall/ccがあるってこと。

Rhinoかな。
