Strange how?  I think it's pretty intuitive: to call «_foo "$bar[@]"»,
write «_foo -Y"${^bar[@]}"» (?).  This is:

- Completely generic: it doesn't depend on the value of «"${bar[@]}"»,
  whether it uses single-letter options or GNU-style long options or
  anything else.

- Composable: it's trivial to pass -bcd through _two_ layers of these
  wrappers, should that ever be necessary.  (Example: pdebuild(1) calls
  dpkg-buildpackage(1) which in turn calls dpkg-genbuildinfo(1), and
  it's possible to pass dpkg-genbuildinfo(1) arguments to pdebuild(1).)

- Requires no new code to implement.  It's simply a repeatable option
  whose optargs are collected in an array.  Both zparseopts and _arguments
  already support this.

*nod*
