Turns out this is also the case on Haiku.

It also eliminates a fork.

`open` opens a file in its default application, using the appropriate tool for the operating system. On GNU/Linux, this requires the common but optional `xdg-open` utility, from the `xdg-utils` package.
Note that this function will not be used if a command by this name exists (which is the case on macOS or Haiku).
