You live and learn :) What a stupid special exception!

    It's not really a special exception, the first argument to split() is a regular expression, irrespective of what the delimiters are, the only special case there being the difference between / / and ' '.

    Some playing around shows it's not an exception: 
    #!/usr/bin/perl

my $string = "Bla\nBlo\nBloe";
print join("|", split('something', $string));

    This code is parsed as 
    ~$ perl -MO=Deparse split.pl 
my $string = "Bla\nBlo\nBloe";
print join('|', split(/something/, $string, 0));
split.pl syntax OK

    The same goes for double quotes. split() expects a regex, but apparently will settle for things in quotes and interpret the string as a regex. Indeed, you live and learn :-)
