There's not much use in doing a global regex match with an anchored regex. Furthermore, a global regex match returns a list of matches, so use a `for`-loop to iterate over them: `use v6; my $line = '124des123'; for $line ~~ m:g/ \d ** 2..3 / -> $match { say ~$match; }` [download] Output: `124 123` [download] Perl 6 - the future is here, just unevenly distributed	[reply] [d/l] [select]

So what is the output of your program and what do you expect instead?	[reply]
