Most likely explanation: Your code was written for Perl >5.18, where
those functions were available, but you're running it on a perl before
<5.18, where those functions don't exist yet.
"qw" is a quote operator for lists of words.
For instance:
my (@array) = qw( hello world );
Has the same effect as if you'd written:
my (@array) = split " ", q[ hello world ];
or
my (@array) = split " ", "hello world";
or
my (@array) = ('hello', 'world');
Obviously it is much easier to write than the last example, and is
impervious to accidentally typing trailing spaces inside the quotes:
my (@array) = ('hello', 'world '); # Hope you see the space!
