-- demo of lua swig capacilities (operator overloading)
eo=require("exception_order")
catch_undef_globs() -- catch "undefined" global variables

a = eo.A()

end

function try3()

-- the following code used to work
-- but now no longer works, as the lua bindings don't throw objects any more
-- all objects are converted to string & thrown
-- it could be made to work, if E1 & E2 were thrown by value (see lua.swg)
--[[

assert(not ok and swig_type(ex)==swig_type(eo.E2()))
]]
-- this new code does work, but has to look at the string
ok,ex=pcall(try1)
assert(not ok and ex=="object exception:E1")

ok,ex=pcall(try2)
assert(not ok and ex=="object exception:E2")

-- the SWIG_exception is just an error string
