how to use assignment operators correctly?

[Cazadorro]

The documentation shows operators but not assigment operators (+= etc...). Core.meta.slang shows some of these operators in use, but I'm confused how to properly handle mutability. Is chaining supported? So doing x = 0; x+=5+=5; would result in x==10? Should we use __ref?

exactly, you can see the usage example on Atomic in core.meta.slang

  __generic<T : IArithmeticAtomicable>                                                                                                 [ForceInline]                                                                                                                        T operator +=(__ref Atomic<T> v, T value)                                                                                            {                                                                                                                                       return v.add(value) + value;                                                                                                     }
