+This research demonstrates once more that functional languages are well suited
+for hardware descriptions: function applications provide an elegant notation
+for component instantiation. Where this research goes beyond the existing
+(functional) hardware descriptions languages is the inclusion of various
+choice elements, such as patter matching, that are well suited to describe the
+conditional assignments in control-oriented hardware. Besides being able to
+translate these basic constructs to synthesizable \VHDL, the prototype
+compiler can also correctly translate descriptions that contain both
+polymorphic types and function-valued arguments.
+
+Where recent functional hardware description languages have mostly opted to
+embed themselves in an existing functional language, this research features a
+`true' compiler. As a result there is a clear distinction between compile-time
+and run-time, which allows a myriad of choice constructs to be part of the
+actual circuit description; a feature the embedded hardware description
+languages do not offer.

+The choice of describing state explicitly as extra arguments and results can
+be seen as a mixed blessing. Even though the description that use state are
+usually very clear, one finds that dealing with unpacking, passing, receiving
+and repacking can become tedious and even error-prone, especially in the case
+of sub-states. Removing this boilerplate, or finding a more suitable
+abstraction mechanism would make \CLaSH\ easier to use.
+
+The transformations in normalization phase of the prototype compiler were
+developed in an ad-hoc manner, which makes the existence of many desirable
+properties unclear. Such properties include whether the complete set of
+transformations will always lead to a normal form or if the normalization
+process always terminates. Though various use cases suggests that these
+properties usually hold, they have not been formally proven. A systematic
+approach to defining the set of transformations allows one to proof that the
+earlier mentioned properties do indeed exist.
