+  Perhaps one of the most puzzling aspects for a beginner when looking at 
+  existing Isabelle code is the liberal use of combinators. At first they 
+  seem to obstruct reading the code, but after getting familiar with them 
+  they actually ease the reading and also the programming.
+
+  \begin{readmore}
+  The most frequently used combinator are defined in @{ML_file "Pure/library.ML"}
+  and @{ML_file "Pure/General/basics.ML"}.
+  \end{readmore}
+
+  The simplest combinator is @{ML I} which is just the identidy function.
