IMHO, these are different tasks.

* "Embed Haskell into some other language" is solved by Literate Haskell

* "Embed some other language into Haskell" is solved by heredocs

Btw., does TH parse this correctly? (If I was TH, I would not):

(the tricky part is "|]" occurring in the quoted text)

Can we escape it?
