That’s probably the functionality you want but as an aside why can’t + overload mutate the caller (left side) and not return anything?

I would expect there to an operator like below in addition to the usual that returns the left side and assigns to the left aside on return.

class operator + (var left: TIntArray; const right: T);

if you’re appending to an array for example:

a += 1;

why should the compiler return the array (a) and then copy it back to the caller in the same place? It’s a just a waste and if the caller is a record it could be costly.
