Well interesting. The fusion requires second order polymorphism, which Felix doesn't support: polymorphic functions can't be passed as values (only instances of them). The funny thing is the reduction rule does NOT actually require a run time polymorphic function, but still seems to require second order overloading to typecheck. -- John Skaller <skaller at users dot sf dot net> Felix, successor to C++: http://felix.sf.net ------------------------------------------------------------------------- Take Surveys.
