ManagedPromise[T]

The ManagedPromise allows you to programmatically control a Promise. For example:

import asyncio
from haskellian import ManagedPromise

promise = ManagedPromise[int]()

async def resolver():
  await asyncio.sleep(5)
  promise.resolve(42)

asyncio.create_task(resolver())

print(await promise) # 42 (after 5 seconds)
