in reply to Modules which improve system() ?

I guess there isn't such a module because for system() all that's about it is in the manual. For running an external programm dealing with the three standard filehandles STDIN, STDOUT and STDERR there's the piped open(FOO,"|-"), IPC::Open2 and IPC::Open3; and then there are IPC::Run and it's brethren.

Implementing those in a single module a la IO::All could be an interesting experiment, but I expect the outcome just to provide a new flavour or calling convention whilst not providing a shield against the underlying complexity to shine through.
