When you go into the other method, you're going into a completely different local scope. The closure properties of the blocks are therefore still extremely useful, because the local scope of the other method can't refer to the local scope of the calling method except through the `glue' that is the block.

Next part will be about blocks in DSL's. @Mr eel, @Taak

Thank you for the suggestion! Next part will be about blocks in DSL’s.

Have you considered discussing the use of blocks in DSLs? They're probably one of the most common uses of blocks — outside of iterators — in Ruby and users unfamiliar with the concepts would at least recognise the code. They're a good place to start tinkering with blocks and getting a good idea of how they work. That's what I've found for myself at least :) A good description!
