Is it possible to add extra code to a running Perl program without stopping it. Basically Im looking at a situation where it will be possible to avoid downtime. I know this is a ridiculous demand. The problem is basically the client for which I work has elaborate processes for even killing processes even in test environment. Providing endless justifications to unfriendly people is a little difficult.It will be nice if there is way to do the modifications without killing the running processes.
I've heard few languages already have this feature. Is it possible to add or modify existing Perl code of a running program without stopping it.
