Export function



Hello again,

here another simple question: How to export a function with save?

I got it running with simple functions e.g. gradient(y,x) := .... with 
save("<filename>", gradient).

But my problem is th efollowing:
matchfix("L[","]");
L[f,g,x] := .....
save("/tmp/show_form.lisp", L[ )

Now I am not able to find the correct syntax to write this function to a file. I 
get an message about an illegal use of delimiter (Space before the L[).

What's wrong?
Thx
Christian
