+These are intended for functions that care what type of data they are
+operating on.  There are two flavours of function.  Functions of the
+first flavour provide type classification only.  Functions of the
+second flavour also check that an argument is of an expected type.
+The type enforcement functions handle only the simplest requirements
+for arguments of the types handled by the classification functions.
+Enforcement of more complex types may be built using the
+classification functions, or it may be more convenient to use a module
+designed for the more complex job, such as @code{Params::Validate}")
