No, it's not a bug. check carefully what's the difference between \z
. and check the following samples:
Update: the third one matches just coz of .* in use. \Z can not keep multiple newlines.
perl -e 'print "match\n" if "foo\n" =~ /.*\z/'
perl -e 'print "match\n" if "foo\n" =~ /.*\Z/'
perl -e 'print "match\n" if "foo\n\n\n" =~ /.*\Z/'
