All languages I use have them: Pascal, C, PHP, C#, Swift, Python, JavaScript.
These are some of the most popular languages in the world right now. You’re
fighting a losing battle sir.
I don't see what the issue is ?
You do have += and the like. They exist, since about as long as I can remember.
You just cannot use it on properties.
Properties have some other restrictions as well:
* You also cannot Use Inc() on integer properties,
* or use Include()/Exclude() on set properties.
* You also cannot do SomeRecordProp.X:=Y;
* or pass them to functions that require var arguments.
And I'm probably forgetting some other limitations.
The += is just another one in the list of limitations of properties.
Basically any operation that requires an address is not allowed.
That += is using an address is an implementation detail of the compiler.
Same as Inc() or In/Exclude(). I don't know the exact reason for this
limitation,
but it's bound to be a good one, otherwise it would have been lifted a long time
ago...
And if someone doesn't like these limitations of properties, (s)he can use fields.
No-one abolished those, after all.
Michael.
