It would be nice to have a block tag where you can append to the current contents of the block, instead of replacing them. This is useful if you need to add a JS file for your template, and the parent template block already has useful links in it (most likely because it overrided yet another parent template). Since you can have nested inheritance, this make preserving whatever the inmediate parent set possible.
