docs: The delete operator
  
  See ECMA 11.4.1
  
  In ECMA 0.19, the description of the delete operator (11.4.1)
  assumes that the [[Delete]] method returns a value. However,
  the definition of the [[Delete]] operator (8.6.2.5) does not
  define a return value. Here we assume that the [[Delete]]
  method doesn't return a value.
  
  @deprecated Use {@link #delete(Object, Object, Context, Scriptable, boolean)} instead
