Does newlisp know...?

[newdep]

It spins now a few days through my head
"how to let newlisp know that the code it is about to execute is newlisp code"

So actualy Befor executing 'any' script, newlisp itself needs to check the content of the script if its pure newlisp.

There are some ways to do this and Im fiddling with the mapping
of (symbols) against the code to read.. but it must be tiny..

Any idea's that might return faster and small code results are welcome ;-)
