If you’re planning to filetest the return values out of a
"readdir", you’d better prepend the directory in question.
Otherwise, because we didn’t "chdir" there, it would have been
testing the wrong file.

DESCRIPTION
Perl 5.6 introduced something called interpreter threads. Interpreter
threads are different from 5005threads (the thread model of Perl 5.005) by
creating a new Perl interpreter per thread, and not sharing any data or
state between threads by default.

➜ perl -MDevel::Peek -E 'Dump(-1)'
SV = IV(0x15f02a0) at 0x15f02b0
REFCNT = 1
FLAGS = (PADTMP,IOK,READONLY,pIOK)
IV = -1
this show -1 is stored as IV internally.
➜ perl -V:ivsize
ivsize='8';
the unit is bytes, so size in bit
ivszie * 8 = 64 .
