Interesting idea. Adding with_context would make it a bit not-so-Ez-Gtk ... unless we named it ... style?

style(:color=>"yellow",:bgcolor=>"purple") {
  window {
    label "Barney loves you ... Run!"
  }
}

 - and style returns whatever returns in its yield.

As for :parent in with_context - I believe it'd flow better if it was automatically placed in the current context parent, like my @storefunc earlier.

And if one doesn't exist - well, it returns itself, so you can then add it as per normal

myvbox = style("...") { vbox { ... } }
mywindow.add myvbox
