% Load this at compile-time to make compiled invocations of the following
% functions fast (and unchecked):
%
% (vector-fetch v i)
% (vector-store v i x)
% (vector-size v)
% (vector-upper-bound v)
% (vector-empty? v)
%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

(load slow-vectors) % for the interpreted versions
(CompileTime (load fast-vector)) % for machine-dependent primitives
