reader (ARGS)

The object is re-blessed into a sub-class of IO::Handle , and becomes a handle at the reading end of the pipe. If ARGS are given then fork is called and ARGS are passed to exec.
So what is happening is you are forking off a process such that the command is "echo" and the arguments to the command are "foo", ">" and "bar." So the behavior your are describing makes perfect sense to me. Maybe you want to 
unless (fork()){
   system ("echo foo > bar");
}

Not sure why you'd open a pipe on a command that doesn't return anything to stdout to be read by a pipe... just my thought....
