[PD] $1 inside a message is not saving data ?

...how is [$1] retains value and [msg] doesn't (except it does anything
other than $n) consistent?

Then, there are those situations where properly formed message is passed
through the msg object with no reported errors but is still malformed
according to the receiving object below msg. An error is thrown by the
receiving object but one has no way of recreating and studying the offending
message...

Another thought is that just like [$1] retains last data value during
runtime, shouldn't [msg] too? After all [msg] retains the rest of the list
inside it not only during runtime but also during save, so why would not it
retain its last data during runtime?
