+ * fixed bugs 10 and 43: VALUES, AND, OR and MEMBER are not suitable as
+ atomic type specifiers, and their use properly signals an error now.
+ * bug fix: an argument count mismatch for a type specifier in code
+ being compiled no longer causes an unhandled error at compile
+ time, but signals a compile-time warning.
+ * fixed simple vector readable printing.
+ * bug fix: DESCRIBE takes more care over whether the class
+ precedence list slot of a class is bound before accessing it.
+ (reported by Markus Krummenacker)
+ * bug fix: FORMATTER can successfully compile pretty-printer format
+ strings which use variants of the ~* directive inside.
+ * bug fix: SEARCH now applies its TEST predicate to the elements of
+ the arguments in the correct order. (thanks to Wolfhard Buss)
