If you're performing an I/O operation on an IO::Path, either it's a metadata operation (e.g. file tests) or you are operating on the whole file (e.g. .lines). In the former case there is no handle; in the latter, the handle exists only while .lines is active; that is, it exists only within the implementation of the .lines method, it is not part of the IO::Path object.
In short, an IO::Path is not a funny-looking handle. IO::Path methods may internally use private handles, and thereby control their lifetimes. (It should be closed when it goes out of scope, i.e. when the .lines method is done, even if it's not explicitly closed.)
