The whole explanation for the difference between block and closure is LTA

[JJ]

Problem

The example for closures includes a block that is "not run", and defines closures as blocks that "do not stand alone as statements".

Suggestions

I don't really see the difference. They're still blocks. Also, the example does not include an actual use case: it simply drops a block in place of a statement. We should always show intent #1748

Removing my assignment, in case someone else wants a crack at it as going to do other things first.
