I experienced this problem in this code:
$_ = "abcdefgh"; say ++$_ until /(\w)<{$0.Str.succ}><{$0.Str.succ.succ}>/ and 
!/i|o|l/ and /(\w)$0.*(\w)$1/;

And `/(\w)<{$0.Str.succ}><{$0.Str.succ.succ}>/` regex is causing it. To
be more specific the `<{}>` parts.

Note: The end result should be 'abcdffaa'.
