Ah, yeah.
I've had to wrangle a lot with those too.
I'm forever trying to do things like:
#declare F0 = function {pattern {bozo}}

and then do something like F0 (x+1, y/2, z)

or F0 = function {pattern {bozo} / <2, 1, 1>}


Functions are certainly challenging in the current implementation.  It takes a
while to get used to what you can and cannot do, and there are a lot of "tricks"
to getting the syntax and expressions worked out to accomplish what one wants.
