%% 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
-record(c_alias, {anno=[], var, % var :: Tree,
pat}). % pat :: Tree
-record(c_apply, {anno=[], op, % op :: Tree,
args}). % args :: [Tree]
-record(c_binary, {anno=[], segments :: [cerl:c_bitstr()]}).
