in reply to RFC: perlfeaturedelta

Excellent idea: I wonder though if it wouldn't be better to extend perldoc with a switch to search the perlxxxdelta pages.

So, just as we already have:

 perldoc -f function
 perlfoc -q FAQ
add a switch:
 perldoc -D delta_thing
I'd also like a -k switch to search for keywords (I regularly forget where things like BEGIN and AUTOLOAD live).
