Well, axiom functions always evaluate all it's arguments first.  So, for
debugging I usually use

output ["x1: ", x1, " x2: ", x2]

If you want cleaner output, you'll have to look into OutputForm. For example,
to print a string without the quotes, you can use message$OUTFORM:

(1) -> message("1")$OUTFORM

   (1)  1
                                                             Type: OutputForm

At least for expressions there is a way to quote and unquote, but I don't have
it present right now.
