The alternative to my is called "implicit scoping", where variables spring to use upon first use, and is present as such languages as http://en.wikipedia.org/wiki/Python_%28programming_language%29 , http://en.wikipedia.org/wiki/Ruby_%28programming_language%29 and http://en.wikipedia.org/wiki/CoffeeScript , and introduces many subtle scoping bugs (it bit me in Ruby at least twice, and also at least twice in Python), and as such is not considered a good idea. "my" is one of the shortest possible ways to declare variables anyway. See: https://news.ycombinator.com/item?id=2864317 (not my link).
