-1.

This is basically a request to add API to the stdlib to turn a two-liner into a 
one-liner.

Diego Palacios  added the comment:

In this case two new functions should be added to the pickle function. I think 
they would be very useful and many users would make use of them.

[Eric V. Smith]

Eric V. Smith  added the comment:

I think it's a bad design to overload a function based on the type of am 
argument. I realize the stdlib does this in a number of places, for older 
functions. I don't think we'd add such a function today.

I might not object to a new pickle API to do this, but I think the best 
approach is to have your own wrapper function.

[issue40074] pickle module dump and load: add support for string file names

[Diego Palacios]

New submission from Diego Palacios :

The pickle functions dump and load are often used in the following lines:

```python
import pickle

fname = '/path/to/file.pickle'

with open(fname, 'rb') as f:
object = pickle.load(f)
```

The load function should also accept a file name (string) as input and 
automatically open and load the object. The same should happen for the dump 
function. This would allow a simple use of the functions:

```python
object = pickle.load(fname)
```

This is what many users need when reading and storing and object from/to a file.
