Copy On Write implementation

[jjjkkkjjj]

I think it is easier for Matft to implement COW than I expected.
Because MfArray has a data class, which is MfData, all we have to do are 2 points. First add “mutating” keyword into conversion method and subscript function. Second check the _isView property in those “mutating” function and then replace the referenced MfData into the new one if the _isView is true.

Should I try to implement it or are you working on it?

@KhalidAl-otaibi
Could you try this if possible?
I’d like to do this, but I’ll be busy until next month due to my work :(
Of course, I’ll help you after next month or I’ll work on this if you can wait until next month :)
