A valid concern. What motivated me to invent this syntax is two concerns:

* if `barBinding=""` has meaning, then what does a "naked" `bar=""` refers to?
* I use nested interpolations heavily in my project, so I was looking for was to avoid typing the full word `translation` all over the place. viz. above, I took liberty at giving meaning to the "naked" key.

P.S. I noticed you started individuals issues. I'm okay with continuing the discussion here, or moving over to the issues.
