 /**
  * A FunctionTemplate is used to create functions at runtime. There
  * can only be one function created from a FunctionTemplate in a
  * context.  The lifetime of the created function is equal to the
  * lifetime of the context.  So in case the embedder needs to create
  * temporary functions that can be collected using Scripts is
  * preferred.
  *
+ * Any modification of a FunctionTemplate after first instantiation will trigger
+ *a crash.
+ *
  * A FunctionTemplate can have properties, these properties are added to the
  * function object when it is created.
  *
  * A FunctionTemplate has a corresponding instance template which is
  * used to create object instances when the function is used as a
  * constructor. Properties added to the instance template are added to
  * each object instance.
  *
  * A FunctionTemplate can have a prototype template. The prototype template
  * is used to create the prototype object of the function.
