Doesn't Fortran 90 have the MERGE(IFTRUE,IFFALSE,CONDITIONAL) function as standard which is similar to the XIF used here? (as usual, Fortran chooses some weird names for its functions). Perhaps the difference with the conditional discussed here is that in a function all the arguments are usually calculated before evaluation, so the conditional may avoid an error if one of the arguments can be invalid depending on the condition. It's a bit unclear from the proposed language addition, however.
