How is dynamic scoping in this case 'more useful'? Imagine function a
written by author A and function b written by author B, both loaded
into an application and each of them working independently, bound
together by an api spec.
Now function a uses typeset IFS="X" to set the field separator to "X"

2. User aspect:
Is anyone aware of a script that intentionally uses the full power of

switched to static?
FWIW, some scripts use "local IFS" to reset IFS to a sane value, and
