Once again, an enum wouldn't readily be able to contribute to your
functor's being able to participate in some method by type signature; i.e.,
I want to support the use case of:
add(Argumented somethingThatTakesTwoArguments);
Maybe this isn't a worthwhile goal, but so far I don't see anything els

Hi Jörg,
I like the simplicity annotations can provide.
As Matt has pointed out Annotations do not define types, which makes it
hard to let the compiler do the validation of the code.
We could implement a custom annotation post processor. But that would
require additional setup for users.

Hi Jorg,
We had at some point talked about whether these could be done with a
simple annotation. I had hoped for something that could be expressed in
terms enforceable by the compiler.

What about in pure functional languages e.g. Haskell?

Hi all,
In Java 8 and Guava the default arity of a Function is 1, but in [functor] it
is 0, IOW, in Java 8 and Guava a Function is by default a UnaryFunction, while
in [functor] it is a NullaryFunction.
What do you guys think of changing the default arity of Function, Procedure and
Predicate
