There are three places along the path where stringification is forced, but none are related to pipes.

  1. `...` is a form of string literal. A string is created from its contents. `...` is the same thing as readpipe("...").
  2. If the shell is required, then the "..." in "`...`" is a shell command, which can only be a string.
  3. Arguments are passed to the child via a variant of the exec system call, which only accepts strings.
