Variable Syntax Doesn't Work?

[AlbinoGeek]

Hello,

It seems that all of the following are broken:

#1
- var selected = (this.selected ? 'selected' : '')
div(class=selected) Selected Item

#2
div(class=(this.selected ? 'selected' : '')) Selected Item

#3
div(class={selected:this.selected}) Selected Item

#4
div&attributes({class:{selected:this.selected}}) Selected Item

I know some rely on #1 , but do they all?

What about this one, that's supposedly documented?

#5
- var attribs = {class: {selected: this.selected}}
div(&dyn = attribs) Selected Item

---

Or even the workaround using a Template helper (polluting the application):

Hello.tpl.jade

#6
div(&dyn=attribs) Selected Item

Hello.coffee

Template.Hello.helpers
  attribs: -> class: 'selected'
