Why does Stream not implement Iterable?
...es reusability, whereas Stream is something that can only be used once — more like an Iterator.
If Stream extended Iterable then existing code might be surprised when it receives an Iterable that throws an Exception the

{
if (foo != null)

However, they have a more stringent restriction -- their key-equivalents, "field names", have to be strings.
Basically, if you were going to create a bunch of instances of a class like:
class Container:
def __init__(self, name, date, foo, b...
Why does ENOENT mean “No such file or directory”?
...ation of Error NO ENTry (or Error NO ENTity), and can actually be used for more than files/directories.
