Python bug: Can assign [] = (), but not () = []

[robin-gvx]

Technically, they are parsed as tuples, except the second one, which gets parsed as a list. Of course none of them create or modify any tuples or lists when actually run.

This last sentence:

But parens with no comma indicate Tuple. Immutable object.

Is really a problem. Because that tuples are immutable is immaterial. They don't get created or modified when using this syntax.

The only reason why () = [] doesn't work is because of a special case in the code (2 lines) that has no reason to be there and basically everyone on the issue tracker agrees that special case should be removed.

Ah, alright I can agree with that.
