No, that is what it is documented to do:
'NULL' or an expression or a vector of an appropriate mode to hold
the list components.
The output type is determined from the highest type of the
components in the hierarchy NULL < raw < logical < integer < real
< complex < character < list < expression, after coercion of
pairlists to lists.
Class information should be lost. You don't give a reproducible example,
would probably do what you want.
