(atomicint) infix ⚛-=

Defined as:

multi sub infix:<⚛-=>(atomicint $ is rwint $value)
multi sub infix:<⚛-=>(atomicint $ is rwInt() $value)

Performs an atomic subtraction 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 subtraction. Underflow 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 subtraction is performed.
