Allow me to add my favorite Perl 6 solutions. The split
version is not tested yet because Pugs::Compiler::Rule
doesn't seem to implement <before>
my $s = "ZBBBCZZ";
my @list = $s.comb: rx/(.)$0*/;
# or if you are very fond on split:
my @list = $s.split(rx/<after (.)><!before $0>/);
The comb-Version seems to be the same as the ruby example, the split-Version shows off the new regex syntax ;-)
