No, you are right. It is meant to be useable on all blocks. We need to
fix the grammar.

Body of the block.

As per spec only in the body of a block.

At the moment we do not consider "each" a part of the body. It is meant to
be executed between iterations, so not really considered a part of the body.
Do you feel it should be considered a part of the body? What about
'before' and 'after'?
