Block Ordering in 3.2.x 'Future Parser'

I have been trying to figure this out by looking through the docs, but I haven't found anything.

The "future parser" included in 3.2.x includes (experimental) support for blocks/lambdas. How is ordering affected inside these blocks? Inside the blocks are all expressions ordered sequentially?

I have a fairly large deployment (node count and software scope) that requires a fairly sequential install/update. We have been using chaining and collectors to define the sequence, which is okay at best. The optimal solution would be to have a set sequence that did not propagate errors through the chain ...

The blocks and lambdas are evaluated in a parse order dependent manner - that is to say, a sequential, top down manner.

So that should make them suitable for the use case you mentioned.

However, I would like to re-iterate that this is an experimental feature, and there could be significant changes to it before it makes it into the stable part of Puppet.
