@hackage haskell-src-exts-qq0.5.0

Allows one to write programs that generate Haskell programs much more concisely and legibly. This package supports:

• Antiquotations, denoted by stealing the splice syntax of Template Haskell, for example [$hs| $x ++ $(Hs.strE "bar") |]. Splices may not nested.

• Antiquoting names in patterns. Names that are antiquoted appear surrounded by double parentheses. For instance:

let f = Hs.name "foo" in [$hs| ((f)) x = x + x |]
