The main change is the elimination of eval-without-macros by the
simpler eval-kl which simply evaluates a KL expression (following a
suggestion by Ramil). I've also added a variable for standard output
as well as input and moved the thaw function out of the set of
primitives where it should not have been. A bug wrt printing large
vectors has been corrected.
Porters should set *stoutput* to the standard output stream.
