They should. I think it is clearly stated in the docs that they
are lowlevel. If it isn't, then this is a bug.

In this case, is the documentation that needs to explain clearly
what the purpose of these functions is. I don't see why they would
need to be changed, considering that they are not even meant to be
used by a "novice user" as you say. :) (They should be avoided by
the expert user too, because REBOL offers a better way to do the
same thing. You have to have a very good reason to use them.. :)
PK> Why should read-io "append" to buffer?
Because that could be exactly what you need. And while this
behavior does not cause any problem to someone that does not need
it (you just provide an empty buffer), the contrary is not true:
if you wanted it to append (because the first packet is not enough
for you to process, for example) and it cleared the buffer you
would be forced to work around it (and at least you'd need to copy
your data, which could be undesirable if you have to copy it again
later while or after parsing).

New users just need correct documentation. Or, better, to avoid
this kind of "unrebolish" functions. ;-)

REBOL is fast because you can write efficient programs with it.
Let's not break this rule. ;-)
