The difference is that if i compile it as a function it has suddenly state
inside it
If i do that as a script it doesnt have the state.
I want the function to be the same thing. No state all the state it gets
should be taken from the arguments that is given in the call(xxxx) method
(just like script does that)
also all our code are standalone functions like
function test()
{
// code
}
if i compile that as a script and say exec() then nothing happens because it
doesnt exec the function but just the scripts (which doesnt do anything)
besides that suddenly having arguments also is not possible for us because
many of our customers use "arguments" we cant just change that. So using a
Script instead of a Function is just not possible
I am currently investigating why it is that function object cant just be as
a script, why we really need to have suddenly a parent and prototype scope
which a Script (which also can have the same function it it) doesnt seem to
need
