Perl::Critic::Policy::BuiltinFunctions::ProhibitSleepViaSelect - Use Time::HiRes instead
of something like "select(undef, undef, undef, .05)".
This Policy is part of the core Perl::Critic distribution.
Conway discourages the use of "select()" for performing non-integer sleeps. Although
documented in perlfunc, it's something that generally requires the reader to read "perldoc
-f select" to figure out what it should be doing. Instead, Conway recommends that you use
the "Time::HiRes" module when you want to sleep.
select undef, undef, undef, 0.25; # not ok
sleep( 0.25 ); # ok
This Policy is not configurable except for the standard options.
