[Feature Request]: Extend Python tuple support for more unusual type creations

[lydia-duncan]

Summary of Feature

Description:
It'd be nice to be able to specify you want a tuple when the Python function returns an array or yields back. Jade suggested that we might be able to get this to work if we rely on PySequence_GetItem or if we do a check for an iterator or generator. But we felt this shouldn't hold up #26946

Is this issue currently blocking your progress?
Nope, just seemed cool to support

Code Sample

(Not complete)

def foo():
  return [1, 2, 3]
def bar():
  yield 1
  yield 2

var t = foo(3*int); // for this to work, you need to do `PySequence_GetItem`
var t2 = bar(2*int); // for this to work, you need to check for a iterator/generator
