If using a partial can cause shadowing then some namespacing should come into play in case e.g. node and node-prime with modified values are both passed in.

* do we want to propagate all variables from the template resource down to every partial?

My guess is yes—I can't really imagine a use case where you want to hide some from a partial. Overwrite it with a different value yes, but not block it. Right?

* I have never tried, but I assume it's possible to assign a value to these variables in a template.

We need to ensure that setting a variable in a partial does *not* propagate up the chain.

In other words, I need to #dup the context before sending it to a partial.

big yes on both points for me!
