For non-trivial programs, each comment might be an entire class, if
doing OO.

I actually do it to help remember where I left off the next day or the
following week after being interrupted.  Sleeping helps wipe memories.
This isn't something new caused by age.  When I coded in my 20s, it was
good to have reminders too. ;)

On any complex code that requires multiple sessions to complete, I'll
also use some tagged comments :bug: :todo: :simplify: to help me recall
what I didn't have time to do the first time.  Sometimes the expected
case is really easy to code, but all the odd situations are much harder,
so they aren't handled on the first pass.
