xt::random::poisson() function parameters do not include the template parameters

[fsibley-necara]

I am trying to create an xt::xarray using the xt::random::poisson() function and have encountered an issue with the templating.

I was able to create a desired array using xt::random::rand() as follows

xt::xarray<int64_t> randA = xt::random::rand({numElems}, lowerBound, upperBound);

However, a call to xt::random::poisson() always fails. The following two blocks of code are examples of how I have tried to call this function. I have varied the types and shapes several times just to be sure that I am not missing something.

xt::xarray<double> localData = xt::random::poisson({1024}, 0.01);

and

auto engine = xt::random::get_default_random_engine();
xt::xarray<double>::shape_type shape = {1};
xt::xarray<float> localData = xt::random::poisson(shape, 0.01, engine);

I see similar failures regardless of how I call this function, and the compiler hints that it is missing type T which is found in the template parameters but not in the function parameters.

Upon examination of xrandom.hpp, type T is missing from the parameters of poisson() whereas it is found in the parameters of other related functions.

        template <class T, class S, class D = double, class E = random::default_engine_type>
        auto
        negative_binomial(const S& shape, T k = 1, D prob = 0.5, E& engine = random::get_default_random_engine());

        template <class T, class S, class D = double, class E = random::default_engine_type>
        auto poisson(const S& shape, D rate = 1.0, E& engine = random::get_default_random_engine());

        template <class T, class S, class E = random::default_engine_type>
        auto exponential(const S& shape, T rate = 1.0, E& engine = random::get_default_random_engine());

Is there any way to call poisson() and not generate such an error?
