[TYPO3-mvc] Fluid inline Array notation?

[Tim Schoch | GSTALTIG]

G'evening

Is there a way to create an array within fluid? I'd like to set some options for the partial sort of like jquery does it with the plugin options:

      <f:render partial="projectList" arguments="{
        project: project,
        options: {
          buttons: {
            delete: 0,
            add: 1
          }
        }
      }" />

This would come in handy in Partials that are used under different circumstances. One could simply check with 
<f:if condition="{options.buttons.add}" /> if a certain piece should be displayed or not.

I know, it would be possible to add every single value as an own argument 
{ optionsButtonDelete: 0, optionsButtonAdd: 1, optionsXY: Z }
But that isn't very practical, if you have sub-sub partials you want to set the options for as you had to pass every single possible option to the child partial. And if you add a new options later on, have fun checking every single render statement...

Is this in the core already and I missed it?
