i use the unwieldy system of a module with create functions and access 
functions. it knows about the record, the rest of the system has to call it.

-module( kalle ).

-export([a/1,b/1,create/2]).

-record( kalle1, {a, b} ).

a( #kalle1{a=A} ) -> A.

b( #kalle1{b=B} ) -> B.

create( A, B ) -> #kalle1{a=A, b=B}.
