+								*Partial*
+A Funcref optionally binds a Dictionary and/or arguments.  This is also called
+a Partial.  This is created by passing the Dictionary and/or arguments to
+function().  When calling the function the Dictionary and/or arguments will be
+passed to the function.  Example: >
+
+	let Cb = function('Callback', ['foo'], myDict)
+	call Cb()
+
+This will invoke the function as if using: >
+	call myDict.Callback('foo')
+
+This is very useful when passing a function around, e.g. in the arguments of
+|ch_open()|.
+
+Note that binding a function to a Dictionary also happens when the function is
+a member of the Dictionary: >
+
+	let myDict.myFunction = MyFunction
+	call myDict.myFunction()
+
+Here MyFunction() will get myDict passed as "self".  This happens when the
+"myFunction" member is accessed.  When making assigning "myFunction" to
+otherDict and calling it, it will be bound to otherDict: >
+
+	let otherDict.myFunction = myDict.myFunction
+	call otherDict.myFunction()
+
+Now "self" will be "otherDict".  But when the dictionary was bound explicitly
+this won't happen: >
+
+	let myDict.myFunction = function(MyFunction, myDict)
+	let otherDict.myFunction = myDict.myFunction
+	call otherDict.myFunction()
+
+Here "self" will be "myDict", because it was bound explitly.
