the variable <code>a</code> will be initialized after <code>b</code> but
whether <code>x</code> is initialized before <code>b</code>, between

thus also the moment at which <code>sideEffect()</code> is called (before
or after <code>x</code> is initialized) is not specified.

In the absence of data races, Go programs behave as if all the goroutines
were multiplexed onto a single processor.
This property is sometimes referred to as DRF-SC: data-race-free programs
execute in a sequentially consistent manner.

<p>
While programmers should write Go programs without data races,
there are limitations to what a Go implementation can do in response to a data race.

  so such references are no longer at risk of using a variable
  after it has been updated by the loop.

  The <code>vet</code> tool now reports calls to

<a href="https://9p.io/sys/doc/compiler.html">this description</a>)
needs no assembler pass in the usual pipeline.
Instead, the compiler operates on a kind of semi-abstract instruction set,
and instruction selection occurs partly after code generation.
The assembler works on the semi-abstract form, so
when you see an instruction like <code>MOV</code>
what the toolchain actually generates for that operation might
