22	Missing support for parallel list comprehension	nibro	nibro	"The parallel list comprehension extension allows several parallel generator clauses:
{{{
  [ (x, y) | x <- xs | y <- ys ] 
}}}
This should be a fairly simple thing to support, the main question will be whether to generalise the existing AST element for list comprehensions or introduce a new one when there's more than one generator clause. I'm leaning towards the latter.
