I know that using a :g command notes the first/last lines of the
range specified as well as marking the already-processed lines. You
don't provide the exact specifications of your transformation (are
there always 3 items separated by pipes? does "foo" ever change?
does indentation change based on a changing function-name?)

However, a simple transformation can be done with

:%s/\(.*\)|\(.*\)|\(.*\)/def foo(x="\1"\r y="\2"\r
z="\3")

which should work for any range you pass it (in the above example,
the whole file, but could just as easily be any Ex range).
