annotation functions #53

I am trying to use annotation functions but I ran accross some problem. Here is my code:

annotation simpleann;
annotation composeann(ann: s);
function ann: annfunc(ann: s) = composeann(s);
solve :: annfunc(composeann(simpleann)) satisfy;

The annotation function works fine if the passed annotation does not take any argument but it crashes if the passed annotation takes an argument as in the example above. The error message is:

mzn2fzn: /home/janho/programs/libminizinc/include/minizinc/ast.hh:198: T* MiniZinc::Expression::cast() [with T = MiniZinc::VarDecl]: Assertion `isa<T>()' failed.

Is this a bug or am I simply hitting the limits of mzn2fzn?

That's a bug (just fixed it).
