The key idea of RFC was not to invite another language for meta-data,

but use PHP language itself. This is a good way to avoid handling a lot of issue, but what I am afraid of is that with this solution, what would happen that people start doing exactly that - inventing another languages for metadata.

I tend to agree - what the proposal basically says is "here's a generic parser, invent a domain-specific language using that parser". Theoretically, people could implement all sorts of weird "operator overloading" behaviour: <<Push($foo >> Translator)>> <<Pipe($foo|lower|escape)>> <<Query($foo ?? '//item[id=42]')>> Do we really need or want that kind of flexibility, just to avoid agreeing a specific structure for metadata? Regards, Rowan Collins [IMSoP]
