Re^2: look-ahead greed changed between perl releases?

[raygun]

So that overrides the greediness precept? The perlre document isn't clear on this, so I wasn't sure which behavior was considered correct.

I no longer have a 5.12.4 handy either: I discovered this issue after upgrading perl and finding my code was no longer working as it had before. Was this a bug in a 5.12.4? I can't find anything in the perl*delta docs that lead me to believe this is an intentional behavior change.

No, it does not override the greediness. The regexp still matches that longest string. But this is just a look ahead. Once the match/substitution is made, the regexp engine starts searching again after the first character matched.
