I really wish clojure would adopt a heredoc syntax to make embed language snippets and docstrings nicer.

And for language embeds, I'm also torned. Because in a way, it is way nicer to use EDN and create a conversion layer from it to the underlying language.
Basically, I feel like there's a lot to gain from sticking to standard Clojure syntax. Like is the case for core.logic, hiccup, garden, etc.
The benefits being, they become first class this way. And then you can build macros on top, create them through functions, etc.
