      Execution traces now use the operating system's clock on most platforms (Windows excluded) so
      it is possible to correlate them with traces produced by lower-level components.
      Execution traces no longer depend on the reliability of the platform's clock to produce a correct trace.
      Execution traces are now partitioned regularly on-the-fly and as a result may be processed in a

operators, in increasing precedence:

Lower-case production names are used to identify lexical tokens.
Non-terminals are in CamelCase. Lexical tokens are enclosed in
double quotes <code>""</code> or back quotes <code>``</code>.

If the divisor is a <a href="#Constants">constant</a>, it must not be zero.
If the divisor is zero at run time, a <a href="#Run_time_panics">run-time panic</a> occurs.
If the dividend is non-negative and the divisor is a constant power of 2,
the division may be replaced by a right shift, and computing the remainder may
be replaced by a bitwise AND operation:
