New submission from Tom Forbes <[email protected]>:
`functools.lru_cache` has a maxsize=128 default for all functions.
If a function has no arguments then this maxsize default is redundant and
should be set to `maxsize=None`:
```
@functools.lru_cache()
def function_with_no_args():
pass
```
Currently you need to add `maxsize=None` manually, and ensure that it is also
updated if you alter the function to add arguments.
