Actual behavior

The debugger console gives a weird result when indexing a dict with a key that doesn't exist in the dict. It prints the key... which is confusing and unexpected.

Expected behavior

It prints that the key doesn't exist. (KeyError)

Steps to reproduce:

• Debug a file that has a dict, for example:

a = {'a': 123}

• Type in the debugger console:

>>> a['a']
123
>>> a['b']
'b' # ???
