[Go] is assign value to pointer an atomic operation?

In system languages it should, however, in C++, consider pointer to member function is 2-word size, which can not be atomic.

That is to say, in Go, quote from Ian Lance Taylor,
both pointer assignments and uintptr assignments are done in a way that can not be interrupted.
