This module defines quasiquoters for haskell-src-exts expressions and declarations.
Antiquotations steal the splice syntax of Template Haskell, so for
x appears antiquoted in
[$hs| $x ++ $(Hs.strE "bar") |].
Expressions appearing inside parenthesized splices are limited to concrete
syntax expressible by Template Haskell's
Exp data type.
Names in patterns can also be antiquoted, using double parentheses. For instance:
let f = Hs.name "foo" in [$dec| ((f)) x = x + x |]
In a pattern context, antiquotations use the same syntax.
