Thanks. (You actually answered questions 2 through 4, not
1 through 3.)
BTW, perldoc.com seems to be out of date also. search.cpan.org is updated 6 times a day, though (see cpan: module and perldoc: links)
(Update: To clarify my point, I am not advocating online docs instead of local use of perldoc. I'm responding to
for those times when you want to link to the POD, and the on-site version is substantially or significantly outdated, you can link to the POD at http://www.perldoc.com.
by mentioning that perldoc.com is itself out of date, and there is another resource that is updated to 5.8.1 and will automatically be updated to 5.8.2 as soon as it is released.)
