Right.  That's *related to* indentation -- it wouldn't be there (we hope)
had the indentation been right.

Sure, but there's also no way for you to spot that something looks
suspicious.  In Python, if something is misindented, it does what you
told it to do, and there's no way for you to tell, by looking at it,
that it isn't what was intended.  In C, if something is misindented,
it does what you told it to do, but it's obvious looking at the code
that something went wrong.

This level of dogmatism about what should always be the case is not
conducive to good software engineering practices.  It is not obvious to
me that it's *always* the case.
