it wouldn't -- i can't imagine any circumstance in which it could.

i'm in 100% agreement. but the manager class is that 'special'
place where all sorts of conditional stuff happens.
it just seems counter-intuitive to everything else in the base rose
class to me.

i have no qualms with that.
i just think that the nature of this new function requires that the
user be made painfully aware of this departure from the standard
workings.
the consensus is clearly otherwise, but let me expand my suggestions to:
a- the name semantically notes that it doesn't alter the object
like other rose functions
b- the function require a flag that the user know whats going on
c- this be placed not in rose::db::object, but in some other
class which extends rose::db::object ( rose::db::objectalt )
i think my issue is that it functions so much like a manager call and
not like a rose object , yet the point of it is to have the
functionality of a manager call in the object itself.
