Yes, that is the indication we are used to see.
So that is why it has to be used like that (it
makes sense to use it like that) even tho
technically it doesn't matter because there is
no parallelism lost in `let' when using `let*'.
So one could use `let*' all the time and not
have to think about it and not have the
bug/confusion when one changes something but
forgets to change the asterisk.
This is what I've heard; I haven't browsed the
C source myself if anyone wants to look for the
lost parallelism. But my bet it'll be even more
difficult to find than the proverbial microchip
in the supercomputer...

(yes
(it is based)
(on what happens on each line) )

Alignment of code is a part of indentation.

The reason is to group items, for example
artefacts,
relics,
treasures,
wierd magical materia,
and other things that are on the same level,
together, to increase "seeing"
and decrease "reading".
PS. If anyone looking at the above example
without understanding it might be you have
a mail client/newsreader that messes that
up. If so, this is your luckiest
computer day of 2018 so far, as that should
be *disabled* first thing and then never
touched upon again, ever.
