Unable to pass a function as an argument

**Description**

I am not able to pass a function as an argument, to python functions.
I found the issue by calling [`matplotlib.animation.FuncAnimation`](https://matplotlib.org/stable/api/_as_gen/matplotlib.animation.FuncAnimation.html).
However, the full code was too long, so I made a minimum example to reproduce.

**How to reproduce**
In codon v0.15.5:
```py
def add(a,b):
return a+b

@python
def debug(f):
print(f, type(f))

@python
def debug_call(f, args):
f(*args)

debug(add)
debug_call(add, (1, 3))
```

Result:
```
((), ())
PyError: 'tuple' object is not callable
