+	// representation of the input value.  Conceptually:
+	//   Formatter[reflect.TypeOf(v)](v) = "v as a string"
+	//
+	// Note that the first argument need not explicitly match the type, it must
+	// merely be callable with it.
+	//
+	// When processing an input value, if its type exists as a key in Formatter:
+	//   1) If the value is nil, no stringification is performed.
+	//      This allows overriding of PrintStringers and PrintTextMarshalers.
+	//   2) The value will be called with the input as its only argument.
+	//      The function must return a string as its first return value.
+	//
+	// In addition to func literals, two common values for this will be:
+	//   fmt.Sprint        (function) func Sprint(...interface{}) string
+	//   Type.String         (method) func (Type) String() string
+	//
+	// Note that neither of these work if the String method is a pointer
+	// method and the input will be provided as a value.  In that case,
+	// use a function that calls .String on the formal value parameter.
