Re: [julia-users] how to i get number of arguments of a function?

[amiksvi]

Great, thanks a lot.
In fact, I also need to evaluate the number of arguments of an anonymous 
function:

julia> function factory(y)
         return x -> x + y
       end
factory (generic function with 1 method)

julia> type Foo
         f::Function
       end

julia> foo = Foo(factory(2))
Foo((anonymous function))

julia> methods(foo.f)
ERROR: ArgumentError: argument is not a generic function
 in methods at reflection.jl:180


Any way to do that..?
