Yes, but i'm not sure if i will add this, you won't be able to declare
things like:

#declare fn_1=IC_BBox(-1, 1) 

And this would lead to a lot of confusion i think.  I might add some
global variables to manage the relevant extends of each macro call.  This
way you could easily design the function as now and just use these global
variables in the 'contained_by{}' statement afterwards (or i could provide
a 'Create_Container()' macro doing this automatically).
