Since you are modifying the buffer text, this will take some effort
anyway.  Once Vim9 script is ready, you can use a :def function where
the for loop should be quite fast.

Perhaps it also works with a map() function.  I've been wondering if
it's useful to add a forEach() function.  But the overhead of invoking a
callback probably makes it slower than a compiled function.
