With `Expected<>` I'd need to craft an `Error` at the end if I don't have a
path to return, but do you mean `Optional<>`? I guess that'd work - but as
`findProgramByName()` returns `ErrorOr<std::string>` I kept the same signature.
Even if returning `Optional<>`, we need a local variable to receive the
`ErrorOr<std::string>` from `findProgramByName()` and inspect it.
In the future (after a release or so) I'd intend for this to be a hard error,
so at that point, the returned error code actually would be printed.
