Good point-- I've added that. |
|
The current autocorrection for code which has a redundant conditional check is just to remove the check-- right now nothing is being done to code which has a conditional check that will never pass (i.e. Thinking about it, that is unreachable code, and so the autocorrection would be just to delete the code entirely.

Ok, I'll handle that cop in a second PR. |
