It's still simply a stylistic question.

As I said, the module was developed with 'use strict' enabled. It's should behave perfectly fine with use strict turned on or not, I'm just leaving it up to the end user instead of forcing it on them.

I will continue to view 'use strict' as a developer tool. It's something to aid in catching "bad" code and "bad" practices while developing, but after a piece of code is done, no development is going on and hence it's not really needed. It does add a slight performance hit (though it is almost negligible, I'll admit).

Besides, there are far too many modules on CPAN that do not behave properly with 'use strict' to really argue over the merits of actually keeping it enabled or not in a submitted module. As long as it was written so that it behaves with use strict and/or $^W, I really don't care.
