Another variation: 

c:\@Work\Perl>perl -wMstrict -le
"print $];
 ;;
 my $s = 'ABCDEF';
 ;;
 my @captures = $s =~ m{ (?= (.{3,})) }xmsg;
 printf qq{'$_'  } for @captures;
"
5.014004
'ABCDEF'  'BCDEF'  'CDEF'  'DEF'

Interestingly, this particular example works exactly the same for all the regex expressions  (.{3,}) and  (.+) and  (.{1,}) on all the Perl versions I have in captivity (all Win32): ActiveState 5.8.9 and Strawberries 5.10.1.5, 5.12.3.0 and 5.14.4.1.
(Of course, output differs between  (.{3,}) and  (.{1,}) but the latter and  (.+) are the same.)
