NAME

Perl::Critic::Policy::BuiltinFunctions::ProhibitSleepViaSelect

DESCRIPTION

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

SEE ALSO

Time::HiRes.
