+
+  HOLCF provides a separate type for continuous functions @{text "\<alpha> \<rightarrow>
+  \<beta>"}, with an explicit application operator @{term "f \<cdot> x"}.
+  Isabelle mixfix syntax normally refers directly to the pure
+  meta-level function type @{text "\<alpha> \<Rightarrow> \<beta>"}, with application @{text "f
+  x"}.
+
+  The HOLCF variant of @{command (HOLCF) "consts"} modifies that of
+  Pure Isabelle (cf.\ \secref{sec:consts}) such that declarations
+  involving continuous function types are treated specifically.  Any
+  given syntax template is transformed internally, generating
+  translation rules for the abstract and concrete representation of
+  continuous application.  Note that mixing of HOLCF and Pure
+  application is \emph{not} supported!

+
+  Recursive domains in HOLCF are analogous to datatypes in classical
+  HOL (cf.\ \secref{sec:hol-datatype}).  Mutual recursion is
+  supported, but no nesting nor arbitrary branching.  Domain
+  constructors may be strict (default) or lazy, the latter admits to
+  introduce infinitary objects in the typical LCF manner (e.g.\ lazy
+  lists).  See also \cite{MuellerNvOS99} for a general discussion of
+  HOLCF domains.
