With Pod::Parser, you just do

it, nothing is output.
Did you flush $out_fh? Pod::Parser did that but Pod::Simple doesn't, so
it's possible if you're doing something short that the entire output was
still buffered.
Pod::Man and Pod::Text use this Pod::Simple method and do have test suites
for it and it seems to work.
See the attached program. The resultant file is 0 length.
Oh! I misunderstood, sorry. parse_from_file() does indeed invoke the
parser with the appropriate actions, but what you meant was that
Pod::Parser's "null" parser, when not subclassed, just printed the POD
back out again, so you could use it as a way to extract the POD from a
file. I believe Pod::Simple's "null" parser does nothing at all, so you
get an empty file.
Yes. I think that's an incompatibility.
If I turn on DEBUGing, it's doing a lot. Is there some trivial way to
extract the pod?
