This experimental fork adds reflective features to Coffeescript

Reflective CoffeeScript aims to be fully compatible with the upstream, vanilla CoffeeScript.

Features added to reflective-coffeescript:

• Reflective function

The syntax @> introduces reflective functions:

square = (x) @> x * x

Reflective functions work similarly to standard CoffeeScript functions:

square(2) is 4

but have their own CoffeeScript source code as a property:

square.coffee is "(x) @> x * x"

Reflective functions can only access 'this' and arguments.

Attempting to access a global variable or a lexical variable defined in an outer scope will result in a compiler error.

 x = 1
 @> x   # Compiler error

As an automatic extra feature, the 'do @>' syntax can be used to fully isolate the lexical scope of a block of code.

x = 1                       x = 1
do -> x = 2                 do @> x = 2
console.log x # prints 2    console.log x # prints 1

x = 1                       x = 1
do @>                       do (x) @>
  x = x * 3                   x = x * 3
  #   ^-- compiler error      console.log x  # prints 3
                            console.log x    # prints 1

Additional ideas are included in ROADMAP.org
