In particular, a compiler must not introduce writes that do not exist in the original program,
it must not allow a single read to observe multiple values,
and it must not allow a single write to write multiple values.

All the following examples assume that `*p` and `*q` refer to
memory locations accessible to multiple goroutines.

      The latency impact of starting and stopping execution traces has been dramatically reduced.
      Execution traces may now begin or end during the garbage collection mark phase.

      To allow Go developers to take advantage of these improvements, an experimental
      trace reading package is available at <a href="/pkg/golang.org/x/exp/trace">golang.org/x/exp/trace</a>.

Go is a general-purpose language designed with systems programming
in mind. It is strongly typed and garbage-collected and has explicit
support for concurrent programming.  Programs are constructed from
<i>packages</i>, whose properties allow efficient management of
dependencies.

<p>
The grammar is compact and simple to parse, allowing for easy analysis
by automatic tools such as integrated development environments.
