I've been reviewing this thread with interest, and I *do* hear what
you're saying.

I think when I originally started learning C (and I am still *very* much
in the learning process, mind you -- so people should take what I say
with a *very* large grain of salt) I looked at the prototype of the
stdlib `malloc' function and thought, "well, it returns a `void *', so I
should cast that return value to the actual type I intend to utilize,
because I don't want a `void *', I want a `char *' (or a `struct foo *'
or what-have-you)," without being fully cognizant of how this is not
necessary, because implicit conversions are done.

So, knowing that it is both (a) not necessary, and (b) *may* cause
harmful unexpected effects, I have changed any of my prior practices and
code that involved casting the return of malloc.  My thinking is, what
is the point of doing something that is both (a) and (b) above, with no
tangible benefit other than to make my code look "better" in some way
by adding these casts.

I can understand where mere "opinion" (as in, "it's just my
opinion/style, it's no better/worse than any other") comes into play
when it comes to mere aesthetic style; eg, tabs vs. spaces, placement of
curly braces, etc., but where the opinion may cause detrimental effects
without any actual upside, I don't get it.
