Re^6: regex at word boundary

This breaks on overlapping palindromes:

adding these two lines to DATA:
nested testest detsen nested
i prefer pi ip referp

produces this output:
line 7:
(0) "nested testest detsen nested"
(7) "testest detsen nested"
(15) "detsen nested"
(22) "nested"

line 8:
(0) "i prefer pi ip referp"
(2) "prefer pi ip referp"
(9) "pi ip referp"
(12) "ip referp"
(15) "referp"

Hrmm....this is what I get: `line 7: (15) "detsen nested" line 8: (0) "i prefer pi" (2) "prefer pi ip referp" (9) "pi ip"` [download] That seems to be correct. Nothing else shows up in line 7, because "testest" isn't a palindrome (but "testseet" is). I guess it's helpful if you indicate what you think the output should be, so I can short circuit this back and forth :) Changing line 7 to this: `nested testset detsen nested` [download] I get this: `line 7: (0) "nested testset detsen" (7) "testset" (15) "detsen nested"` [download] What did you expect on the 2 lines you added? -QM -- Quantum Mechanics: The dreams stuff is made of	[reply] [d/l] [select]

I'll get what you get, I strongly suspect, when I'm not on a v5.6.1 Perl implementation. So your stuff does work with sufficiently current Perl. I'll rerun the speed comparison when I'm home and have access to v5.8 Be Appropriate && Follow Your Curiosity	[reply]
