I am aware that I am passing non existing arguments here, which is why
my method of creating a list of the environment "as.list(environment())"
seems to fail in this case.
What I need is a way to just skip non existing objects when I create my
list. In my given example I was intending to receive an empty list,
since no valid arguments were passed to test2().
In other words: I want a list containing all _existing_ variable/value
combinations and just skip the missing ones.
Thanks again for your time
