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
use Time::HiRes;
sleep( 0.25 ); # ok
This Policy is not configurable except for the standard options.
Time::HiRes.
