CoffeeScript and significant whitespace
Jeremy Ashkena has eliminated the need for those pesky periods to delimit scope. Indentation is now the indicator. And hey, I like that because I like Python ;)
Example:
http://github.com/jashkenas/coffee-script/blob/whitespace/examples/whitespace.cs
Note this is in a new branch of the project called ‘whitespace’. I think it probably goes without saying that since CoffeeScript is alpha, the whitespace branch is even more alpha!
Awesome work Jeremy :)
