Hi all, I have a general question. I would like to compile the following function:

```auto
def test1(t):
    return t+1

def test2(t):
    return t+2

fs_compiled = [nb.vectorize(f) for f in [test1,test2]]
@nb.njit()
def check_nb1(t):
    out = sum(
        [
            fs_compiled[x](t) for x in np.arange(2)
        ]  
    )
    return out

```

However, when I run the code (`check_nb1(10)`), it gives the following error: `Cannot type list element type <class 'numba.np.ufunc.dufunc.DUFunc'>`. Could anyone please help me? Thanks a lot!
