Comment (by polkovnikov.ph):

 I don't actually think there's a lack of interest in this functionality.
 It could finally let programmers to write TH-based translation libraries.
 For example, one could create `javascript` such that `print $ javascript
 sort` generates JS code for list sorting, effectively reusing Prelude.
 Also, some language extensions like Megacz's generalized arrows could
 become libraries.
