Comment:

 The current version of the vectoriser can't handle type classes yet;
 hence, the error.

 BTW, in the current version of DPH, you need to use the simple mock
 Prelude from package dph in all code that ought to be vectorised — if you
 use the standard Prelude, you will get similar errors (even without using
 type classes).  We will lift these restrictions in future versions.
