Can't seem to overwrite elements of a writable list_of

[DavisVaughan]

cpp11::cpp_source(
  code = '
  #include "cpp11/integers.hpp";
  #include "cpp11/list_of.hpp";
  
  [[cpp11::register]]
  cpp11::writable::list_of<cpp11::writable::integers> test() {
    cpp11::writable::integers x{1, 2};
    cpp11::writable::integers y{3, 4};
    cpp11::writable::list_of<cpp11::writable::integers> out({x});
    out[0] = y;
    return out;
  }
')

test()
#> [[1]]
#> [1] 1 2

Thank you for opening the issue and for supplying a reproducible example, it is a big help!

This should now be fixed and work how you were expecting.
