%% Possibly the following type declaration does not belong here...

-type beam_instr() :: 'bs_init_writable' | 'fclearerror' | 'if_end'
                    | 'remove_message' | 'return' | 'send' | 'timeout'
                    | tuple().  %% XXX: Very underspecified - FIX THIS

%%
%% This is a labeled_export tuple returned by beam_lib:chunks/2.
%% It has the form {fun_name(), arity(), label()}.
%% DOES NOT BELONG HERE - IT BELONGS IN beam_lib.hrl BUT THERE IS NO SUCH FILE
