the rest of paper is: \hs{[a|n]}. Where the \hs{a} is the element
type, and \hs{n} is the length of the vector. Note that this is
a notation used in this paper only, vectors are slightly more
- elaborate in real \CLaSH\ programs.
+ verbose in real \CLaSH\ descriptions.
% The state type of an 8 element register bank would then for example
% be:
