Feldspar is a domain specific language with the goal of raising the
level of abstraction for performance sensitive, low-level code.
Feldspar is a functional language embedded in Haskell, which offers a
high-level style of programming. The key to generating generating
efficient code from such descriptions is to use a high-level
optimisation technique called vector fusion. Feldspar achieves
vector fusion for free by employing a particular way of embedding the
language in Haskell by combining deep and shallow embeddings.
