Took me some days to figure out why I was able to create a final .pl
file with pp but every invocation of the generated .pl file created a
busy loop.

Finally I found the reason for this: I called my main perl file I used
as the input file for pp main.pl. When I renamed it to hello.pl the busy
loop was gone.

Would save other beginners of pp a lot of time if pp will reject main.pl
as input file ;-).
