Failure when defining a function with no args

[JockLawrie]

Hi there,

I have users defining (simple) functions as strings in a config file, which ultimately get made into functions.
Often a user has a function return a constant.
My code fails in this case, MWE below.
Any ideas where I'm going wrong?

using RuntimeGeneratedFunctions
RuntimeGeneratedFunctions.init(@__MODULE__)

s = "() -> 1"
ex = Meta.parse(s)
f = @RuntimeGeneratedFunction(ex)

If I set s = (x) -> 1 it works, but then I don't have a function of 0 arguments, which is required by downstream code.

PR #29 would solve this problem.
