I am inclined to the fact that it's better to rename `objectarray` to
'mutabletuple' in order to be explicit about what is that.
'recordarray' is a factory function that make exactly the same as
'namedtuple' factory does (except that it create subclass of 'mutabletuple'
and make '_replace' to update the 'self', not make a copy). So may be it's
better to call it as 'record' or 'recordtype', or even 'recordfactory'?
