In the above case, I'd just use

:v/function/s/\<fn\>/a:&/g

which reads a little more cleanly to me. I confess I don't
use/write vim functions often, so I frequently forget the "a:"
scope modifier for function arguments until I actually test/run
the function and get errors. Enough bugs and it could have been
called a FootGun function ;-)
