I tried that, but it seems to think I mean to override 
super.fun(uint) instead of super.fun(uint, float).

Looking at my code again, one of them is templated with a range 
interface. I think that might be the problem, though I can't 
figure out how to fix it. Wrapping the alias in a template block 
doesn't seem to do it.
