Subject: Lazy load Carp on croak
Download (untitled) / with headers
text/plain 232b
This is reducing memory footprint of IO::Socket::IP by postponing the load of Carp and also avoiding the global import. View suggested patch at https://github.com/atoomic/IO-Socket-IP/commit/412912958ba3191e877f071de64891dc9429cad7

I've never been a huge fan of this sort of lazy loading. It might have made sense in the mid-1990s, but RAM is sufficiently cheap and disk spindles sufficiently fast that really there's very little cost to loading modules like Carp. In addition, deferring the loading until later breaks in fantastically hard-to-debug ways in those odd situations such as chroot'ing and similar, where the application simply can't touch disk after it's started up. Such situations are precisely when you do want to rely on good debug logging to work out what's going wrong. -- Paul Evans
