The following code works just fine in python, and when using njit. However, when I set NUMBA\_DISABLE\_JIT=1, it will print an empty list. Is this the expected behavior?

```auto
from numba.typed import List
from numba import njit

@njit
def bar():
    a = 12.1
    b = 13.2
    return List([a, b])

c = bar()
print(c)

```

Yes, I believe this is known: [`typed.List` ignores constructor arguments when jitting is disabled · Issue #6001 · numba/numba · GitHub](https://github.com/numba/numba/issues/6001) – it’s a bug which initially seems trivial to fix but then turns out to be very, very hard.
