Of course you have to run this in a directory that doesn't contain
any file matching /^[YN]{5}$/.
Not true. The {} notation doesn't care whether files of that name
actual exist. I tested like so on Mac:
% touch YYYYY
% perl -le 'print for glob"{Y,N}"x5'
YYYYY
YYYYN
YYYNY
YYYNN
YYNYY
YYNYN
YYNNY
YYNNN
YNYYY
YNYYN
YNYNY
YNYNN
YNNYY
YNNYN
YNNNY
YNNNN
NYYYY
NYYYN
NYYNY
NYYNN
NYNYY
NYNYN
NYNNY
NYNNN
NNYYY
NNYYN
NNYNY
NNYNN
NNNYY
NNNYN
NNNNY
NNNNN
