All Ruby blocks (and methods) return a value. They return the value  
of the last statement in the block.
But only if you explicitly use it.
Assign it to something, or use return if you want it to be obvious.

The convention is simply
{} for one-line
do-end for multi-line

You don't have to follow these rules. It is up to you.
