To me the following look the same:

	Path('file').read_text()
	open('file').read()

The first presumably creates a Path object while the second creates a 
file object. Why should I assume that the Path object closes the 
underlying file object after the method is called? I mean maybe my 
assumption is bad, but I doubt I'd be the only one making it given how 
open() works and that it looks similar superficially.
