 What is the syntax exactly ? Does it make 'strict' a reserved keyword ?

It doesn't make "strict" be reserved.

With regards to multiple blocks, there are a few possible approaches:

* First block affects subsequent blocks, only it can declare strictness (my f=
avourite)
* Per-block
* Use of directive prevents use of end tags, and thus use of multiple blocks=


I think the first makes the most sense. It's what namespaces do, after all.

Thanks.
