Note: This class is a Rakudo-specific feature and not standard Raku.
# basic usage
use Telemetry;
my $t0 = Telemetry.new;
# execute some code
my $t1 = Telemetry.new;
my $period = $t1 - $t0; # creates Telemetry::Period object
say "Code took $period<wallclock> microseconds to execute";
A Telemetry::Period object contains the difference between two
Telemetry objects. It is generally not created by calling
.new, but it can be if needed. For all practical purposes, it is the same as
the Telemetry object, but the meaning of the values is different (and
the values are generally much smaller, as they usually are the difference of
two big values of the Telemetry objects from which it was created).
