Is it a compiler bug?

I don't think its a bug, per se, but an effect of attempting to overload a function 
template with an ordinary function.  Try providing a dummy specialization of the template 
instead, such as:

# static Any opCall (T) (T t) {
#   return (new Any).assign(t);
# }
#
# static Any opCall () () {
#   return new Any;
# }
