".{} foo" and its variants are bad style because they're essentially
"magic characters". Making div implicit when you're using "." and "#" to
create CSS-sensitive attributes makes sense, because the CSS attributes
tend to denote structural elements of a document, and a div is the most
common such element.
However, without CSS, "." and "#" lose all semantic meaning, becoming
essentially arbitrary shorthand for "%div". Haml is about semantics;
having arbitrary characters work as shortcuts just for the sake of them
being shortcuts is antithetical to that.
".{}" won't be deprecated, as it's not a feature. It's an error in Haml
syntax, even though it doesn't throw an error. In the next major release
of Haml, and maybe in incremental releases before that, it will throw an
error, so you certainly shouldn't use it.
I hope that answers your question.
