%% Purpose : Core Erlang syntax trees as records.

%% It would be nice to incorporate some generic functions as well but
%% this could make including this file difficult.

%% Note: the annotation list is *always* the first record field.
%% Thus it is possible to define the macros:
%% -define(get_ann(X), element(2, X)).
%% -define(set_ann(X, Y), setelement(2, X, Y)).

%% The record definitions appear alphabetically
