Hmm, @sarina, I don't think that variable limits to student access:
(xmodule_modifers.py: lines 60-66)```
if isinstance(block, (XModule, XModuleDescriptor)):
          if view == 'student_view':
              # The block is acting as an XModule
              css_classes.append('xmodule_display')
          elif view == 'studio_view':
              # The block is acting as an XModuleDescriptor
              css_classes.append('xmodule_edit')
```
