Hi all, 

my $s = '::';
my @fields;
for my $s ( '::', ':', '' ){
 for my $lim ( 0, -1 ){
  print "s=$s, limit=$lim\n";
  @fields = split( ':', $s, $lim );
  print "fields=".@fields."\n";
 }
}

[download]
the output is 
s=::, limit=0
fields=0
s=::, limit=-1
fields=3
s=:, limit=0
fields=0
s=:, limit=-1
fields=2
s=, limit=0
fields=0
s=, limit=-1
fields=0

The discontinuity in the output from split(':','',-1) (last line) is evident. A '' is certainly an "empty field". (Whether it is leading or trailing possibly depends on the way you look at the string :):).)

A '' should be considered a trailing empty field for any delimiter, and split in the last case should return ('').
