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.
You of course are aware of what a pain it is to apply this logic?
