For the same reason ",1,2,3" when split with /,/ produces ("", 1, 2,
3). The regex you pass to split is the field separator. The fact
that it finds a field separator before it finds a field data means the
first field is empty. You may find that what you want is a normal
regex like
my @numbers = /(\d+)/g;
