hi, if i have a task that can take in a very large number of parameters, is it possible to pass them all in as a collection to the task? eg:

with Flow(...) as f:
   param_1 = ...
   param_2 = ...
   ...
   param_n = ...
   x = my_task([param_1, param_2, ..., param_n])

Looks like it 🙂

In [2]: from prefect import Flow, task, Parameter

In [3]: @task
   ...: def foo(params):
   ...:     print(params)
   ...: 

In [4]: with Flow("foo") as flow:
   ...:     x = Parameter("x", default=1)
   ...:     y = Parameter("y", default=2)
   ...:     foo([x, y])
   ...: 

In [5]: flow.run()
