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 my $string = "Bla\nBlo\nBloe"; print join('|', split(/something/, $string, 0)); 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 :-)
