Parallel comprehensions not allowed in Template Haskell quotes
When my code contains
[| [ (x,y) | x <- [0..10] | y <- [0,5..50] ] |]I get
Exotic statement not (yet) handled by Template Haskell
[x <- [0 .. 10] | y <- [0, 5 .. 50], (x, y)]Interestingly, the node to handle parallel comprehensions (ParS) already exists in Template Haskell, but the code in !DsMeta is missing.
I will submit a patch shortly.
