/* Initialize the container 'dest' as per 'oplist' INIT operator
and fill it with the given VA argument
assumed to be pair (key,value) with the SET_KEY operator.
If key (resp. value) is itself in the form ( ) and the
oplist defined an EMPLACE_TYPE operator, performs an emplace insertion
by construction an emplace call with no suffix.
