  Well, is the ?: operator listed as valid operator in user-defined
functions?

  While it might not be very clear from the documentation (it should
perhaps be), the SDL and the user-defined functions are basically two
completely different and independent languages. They somewhat resemble
each other, but the user-defined functions are basically a language
inside the SDL, not SDL itself. They are even interpreted at
completely different levels. For this reason not everything that
works in the SDL works in the user-defined functions.
  You can create the body of a user-defined function using SDL, but
that's just kind of user-defined function metaprogramming, that is,
a program (in a different language) which creates a program (in the
other language).
