Topic: Nothing is named `Task` in this scope

How do i use tasks in function declarations?

i tried to make this example and it won't let me

doSomething : {} -> Task Str *
doSomething = \{} -> Task.succeed "Hi"

i'm using these imports

imports [
        pf.Stdout,
        pf.Stdin,
        pf.Task.{ await },
        pf.Task
    ]

try replacing the last two lines of the imports with:

pf.Task.{ Task, await }

Richard Feldman (Dec 03 2022 at 01:19):

that basically says "import the pf.Task module and bring the Task type and the await function into my local scope"

Okay now it works, thanks!
