Performs type-safe access to the contained object.

For (1-3), the program is ill-formed if `ValueType` is not a reference and std::is_copy_constructible <ValueType>::value is false.

### Parameters

operand | - | target `any` object

### Return value

1) Returns *any_cast< std::add_const_t < std::remove_reference_t <ValueType>>>(&operand).
2-3) Returns *any_cast< std::remove_reference_t <ValueType>>(&operand).
4-5) If `operand` is not a null pointer, and the `typeid` of the requested `ValueType` matches that of the contents of `operand`, a pointer to the value contained by operand, otherwise a null pointer.

### Exceptions

1-3) Throws `bad_any_cast` if the `typeid` of the requested `ValueType` does not match that of the contents of `operand`.
