The above should print ten times. But it only prints the five even numbers.
That is a bug isn't it?

yes, but its ancient. It is to do with the implementation of blocks and specifically block temporaries. Both blocks bind to the same "i". So when you evaluate

block value: i + 1

the 1 to: do:'s i gets incremented.

Try this with my closure implementation (http://www.mirandabanda.org/cogblog/downloads/) and it is fixed.
