range: 'range' object is not subscriptable

[corona10]

Range object should support get_item operation :)

gpython

>>> a = range(10)
>>> a[0]
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
 FIXME line of source goes here
TypeError: "'range' object is not subscriptable"

python3

Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 26 2018, 23:26:24)

>>> a = range(10)
>>> a[0]
0

I can't imagine why you'd want to do that, but yes it looks like a bug :-)

Oh, I am finding out feature with not compatible with cpython3.
so sometimes I write something strange code.
And this bug was found from practical code and this code is just an essential part of the bug to reproduce.

I see!

In idea: at some point we could use go-fuzz to find code which doesn't behave the same way in gpython and python3.

@ncw Yeah it would be a good choice!
