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 favourite) * 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. -- Andrea Faulds http://ajf.me/
