It is. Apart from ++index, this is literally the same as:

  let ch = if index < strlen then str.charAt(index) else 0

Eminently readable and less boring than long if/else chains in Python.

It's not. To be easily human-parsable you want to do one thing at a time. It's that incrementation that you've ommited that messes things up.

On a side note, having gotten used to newer languages, an option type sure is a nice thing.

You can write in a very similar way in python too if you want to. I think I'd argue this is cleaner syntax, even.

    >>> foo = 10
    >>> bar = foo if foo > 5 else 0
    >>> bar
    10
    >>> bar = foo if foo < 5 else 0
    >>> bar
    0

IDK,

"for ch in index:"

reads pretty cleanly to me.
