What do you do now? My fellow Perlsuers of Wisdom, what would be some of your favorite ways of preventing piped,"&&ed","||ed",";ed", etc. commands?

It all depends on how it's going to be used. If it's going to be a part of something that will be evaluated by a shell, take every precaution you can (although quotemeta often is enough). When using system calls, use the list forms of system, exec and IPC::Open2::open2 and IPC::Open3::open3.

Custom tainting can be done using Taint, but I have yet to find out how that works myself.
