Why not make 'in' work for arrays (and strings also)?

Good thing that compiler recommends what to use instead, but
why not just make it work for any container?
join the dark side of second best language :)
```python
a = [1,2,3]
d = dict(zip(a, ['a','b','c']))
if 3 in a:
print("found in array")
if 3 in d:
print("found in keys")
if 'a' in d.values():
print("found in values")
```
