It would be nice if the indentation for Python could work like these two examples:

A. Indent four spaces for opening chars: [ ( {
Example:

def foobar(<ENTER>
    <CURSOR>):
    
Typing bar will make the code look like:

def foobar(
    foo, bar):


B. Indent to just after the opener for chars: [ ( {
Example:

def foobar(foo,<ENTER>
           <CURSOR>):

Typing bar will make the code look like:

def foobar(foo,
           bar):
