 The relations between datatypes and algorithms is given in the (approximately
 commutative) diagram shown below. Black lines indicate CPU algorithms, green
 lines indicate CUDA algorithms, blue lines indicate SYCL algorithms, and brown
-lines indicate Futhark algorithms. Solid algorithms are ready for use, dashed
-algorithms are in development or future goals. Data types for different
-heterogeneous platforms are contracted for legibility, and identities are
-hidden.
