Python's forced indentation certainly doesn't burden me at all.  I
don't know about you, but I indent whether I have a block delimiters
or not.  Python doesn't force me to do anything I wouldn't do anyways.

What *is* burdensome is having to use block delimiters, AND to make
sure they are properly sychronized to the indentation.

Well, if you're complaining about your lack of freedom, then you're
complaining about your freedom to write unreadable and misleading
code.  It's a freedom I don't care for (usually).

No, not any more than C would.  Do you not indent in C?  If your C
code runs against the margin, is your solution to simply stop
indenting, and run all the blocks together?  (If it is, then you have
worse problems than being forced to indent.)

And, as a matter of fact, I never exceed 79 columns in any of my
Python code.  And I use eight-space tab stops.  And my editor doesn't
have horizontal scrolling; it wraps.
