Thomas, thanks for the detailed example!

I was reading over the weekend about shadow-cljs and it is definitely an 
intriguing approach. However, my motivation for these es6 experiments is to 
eventually bring them into a larger project I am working on, which already 
has an existing boot build framework. Realistically, I'm probably going to 
have to make it work within the boot ecosystem.

I'm curious why you think :foreign-libs is deeply flawed. It is my 
understanding that :npm-deps are also converted to :foreign-libs under the 
hood, and it seems like a lot of work has been put into these features over 
the last year or two. If the approach was deeply flawed, this would seem 
like a big deal.
