Problems with IupLua, wlua.exe and arguments passing.

Well, there will be no problem discussing it here, given that we
don't
actually have a forum for LfW (yet)
Ok then let's go. Issue number one (I'll split my issues and send them
one by one):
To show up the problems, I wrote the following script:
-=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=-
require"iuplua"
local lines={}
for k,v in pairs(arg) do
lines[#lines+1]=string.format("arg[%d]=%q",k,v)
end
lines=table.concat(lines,"\n")
iup.Alarm("Show Args",lines,"OK")
-=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=-
When I invoke the script with "wlua ShowArgs.wlua" everything is fine.
When I add some arguments "wlua ShowArgs.wlua ONE TWO THREE", nothing
happens.
Wlua seems to exit silently without any error message at all.
I have changed the script to
-=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=-
local lines={}
for k,v in pairs(arg) do
lines[#lines+1]=string.format("arg[%d]=%q",k,v)
end
lines=table.concat(lines,"\n")
arg={}
require"iuplua"
iup.Alarm("Show Args",lines,"OK")
-=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=--=-
Now everything is works, even with arguments.
It seems, the require"iuplua" triggers an argument evaluation.
Is this a bug? Or a feature? How can I pass arguments to my script
without dirty tricks?
(Using the standard "wlua ShowArgs.wlua -- ONE TWO THREE" does not
help either.
