If I understand this correctly the author thinks it is important to turn on warnings for the script but not necessary for modules it uses. Hence at least for perl >= 5.6 they go for the lexically scoped warnings.

I tend to look at this as the author saying: I must have warnings on in my code, I'll try not to turn it on in the modules I use so they don't break in strange ways, but in perl's before 5.6 I have no choice.

I guess they're trying to make their code as compatible as possible with perl's before 5.6 and strangely written modules, but it does seem rather cargo-cultish. On a side note: perl 5.6 has been out a long time, so I don't really see the point. Why would someone run something new like Subversion, and not bother to upgrade their ancient Perl? Upgrading parts of your system while other parts are left to rot in legacy mode just seems like trouble.
