More flexible how?
If I don't want the output from the command, I just use system:
   system("command");
   # optionally check return status here

Can you even do this with pipes?

In the case of using backticks to get back the output you could maybe use a
pipe, but how would it be "more flexible" then simple backticks and some
creative redirection operators (in case STDERR is required instead of
STDOUT, for example) usage?

Not flaming, just wondering... :-)
