# `Value` is the base type of the primitive types (`Nil`, `Bool`, `Char`, `Number`),
# `Symbol`, `Pointer`, `Tuple`, `StaticArray` and all structs.
#
# A `Value` is passed by value: when you pass it to methods,
# return it from methods or assign it to variables, a copy
# of the value is actually passed.
# This is not important for nil, bools, integers, floats, symbols,
# pointers and tuples, because they are immutable, but with a mutable
# `Struct` or with a `StaticArray` you have to be careful. Read their
# documentation to learn more about this.
struct Value
  # Returns `false`.
  def ==(other)
    false
  end

  # Returns a shallow copy of this object.
  #
  # Because `Value` is a value type, this method returns `self`,
  # which already involves a shallow copy of this object because
  # value types are passed by value.
  def dup
    self
