Currently I've discovered that Sub::Signatures does not run efficiently unless I postpone some work to a CHECK or INIT block. I'm trying to work around this but in the meantime, since CHECK and INIT do not function properly under mod_perl, I'm wondering if there is a standard workaround that's fairly transparent to the end user? I'd rather not force them to explicitly call a setup method. Since the code uses a filter, I suppose I could explicitly set up the setup call for them, but that seems rather ugly.
