<p>
The Go memory model specifies the conditions under which
reads of a variable in one goroutine can be guaranteed to
observe values produced by writes to the same variable in a different goroutine.

Programs that modify data being simultaneously accessed by multiple goroutines
must serialize such access.

the corresponding code point.  If the iteration encounters an invalid
UTF-8 sequence, the second value will be <code>0xFFFD</code>,
the Unicode replacement character, and the next iteration will advance
a single byte in the string.

The iteration order over maps is not specified
and is not guaranteed to be the same from one iteration to the next.
