There are a few modules on CPAN that I use over and over and over. Every single one of them exports a set of functions.

The one module that I should use more that I don't (and won't unless forced to) is File::Spec. I HATE the pseudo-OO interface with an absolute passion. Oh, I understand why it was written that way and I'm not sure I would've written it differently under the hood. But, the UI just sucks so badly that it hurts.

There are also a few modules on CPAN that I use a lot that provide an OO interface. This is because there is state information that needs to be preserved.

Yes - CGI is OO. The functional interface is an absolutely horrid and I refuse to use it.

The point is that you should provide a functional interface if they are side-effect-free functions. If there is data that needs to be preserved across function calls, then you should provide an object.

My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
