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.
