Re^2: Limiting number of regex matches

Or Maybe this:

use warnings;
use strict;

my $str = 'dog dog dog dog dog';
print join " " => ( split /\s+/, $str )[ 0 .. 2 ];
[download]

Output
dog dog dog

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.

That doesn't limit the number of matches, it still counts/matches every single dog in the string	[reply]

Yes, why use a regex to match for an obvious substring in this case, when a string could be splited into an array, a slice of that which got the required output printed? Please, don't forget that the OP also asked among other things "..Is there no other way.."? Am simply showing, some other ways, in this case. If you tell me, I'll forget.
