(atomicint) infix ⚛+=

Defined as:

multi sub infix:<⚛+=>(atomicint $ is rw, int $value)
multi sub infix:<⚛+=>(atomicint $ is rw, Int() $value)

Performs an atomic addition on a native integer. This will be performed using hardware-provided atomic operations. Since the operation is atomic, it is safe to use without acquiring a lock. Evaluates to the result of the addition. Overflow will wrap around silently. If $value is too big to unbox to a 64-bit integer, an exception will be thrown. If $value otherwise overflows atomicint then it will be silently truncated before the addition is performed.
