Fastruby 0.0.8 released with support for lambdas

Fastruby is a gem which allows to execute ruby code much faster than normal, currently in a state of transition between a spike and a usable gem, it is released when possible with incremental improvements.
The version v0.0.8 was released with the new feature of supporting lambdas. Functional improvement does not appear to be important, but the underlying internal implementation will allow new features in the next release such as the support for proc and continuation objects.

Install

You can clone the repository at github:

git clone git://github.com/tario/fastruby.git

Or install it using gem install:

gem install fastruby

New Features

• Support for lambdas
  
• Internal: new structure to represent stack
• Better implementation of break statement
  

Examples of code being supported

Scope retention (lambda has a reference to the scope where it was created)

1. require "fastruby"  
2.   
3. fastruby '  
4. class X  
5.   attr_accessor :lambda_set, :lambda_get  
6.   def initialize  
7.     a = nil  
8.   
9.     @lambda_set = lambda{|x| a = x}  
10.     @lambda_get = lambda{a}

15. x = X.new

17. x.lambda_set.call(88)  
18. p x.lambda_get.call  

require "fastruby"

fastruby '
class X
  attr_accessor :lambda_set, :lambda_get
