Yes, but make sure you do it right. I've been caught out by passing something like a Path::Class::File object, which stringifies just fine as a file path, to modules like this if only they'd just treat it as a string -- but instead overjealous checking spots that it's a reference and declines to stringify it. If you get a reference to a blessed object and that object has overloaded stringification then please just treat it as a string, not a reference. Smylers
