Yep, true; thanks, fixed.

I’ve also rewritten the sentence in the dynamic class-based model section.

properties “d” and “e” have been copied (as a result, structure of D is: {a, b, c, d, e}); however, methods {method1, method2}) have not been copied.

I think you have a typo here,should the sentence be properties “a”,”b” and “c” have been copied ??
