GNU ld supports "pragmas" which cause the use of certain functions

other partial functions.
would you include all partial functions in this, such as head?
I'd like to, but IMO head is a little more acceptable because lists
aren't binary like Maybe. fromJust really is the Haskell equivalent
of dereferencing a pointer without checking if it's NULL, aside from
being more reliably detectable.
