from my point of view, all are script variables: avps, references to sip

most of the programming languages use $ for that. It is what was decided
long time ago in openser when pseudo-variables were introduced in core.
Basically, there are classes of script variables, some accepting dynamic
names (like avps $avp(...), headers $hdr(...), private $var(...) and
shared variables $sht(...) a.s.o.).
I do not see reason for a special character for certain classes, like
avp or select. It is much much clearer to have:
$avp(name)
$sel(name)
rather than:
$name for avps
@name for selects
&name, %name etc. for what so ever variable class

whose confusion?
like the discussion on lookup_domain function revealed, it is confusing
that the same prefix ($ char) is used for two different things.
Lot of code
and config depends on PV frameworks, so if you feel less
confused, just use select instead of PV, both are available, it is your
choice to use one of them. You can just not load pv module you have not
much to do with PVs.
that indeed is a viable option.
