Description
Is your feature request related to a problem? Please describe.
The Option module includes traverse and sequence operations for use with Async (per #298), but not Task. Since the prevailing wisdom for F# code going forward seems to be "prefer Task", having these functions would encourage that choice.
Describe the solution you'd like
I'd like the following functions implemented in the Option module:
// traverseTask: ('a -> Task<'b>) -> 'a option -> Task<'b option>
// sequenceTask: Task<'a> option -> Task<'a option>Additionally, some other permutations that would be useful:
To match functions added in #321
// traverseTaskResult: ('a -> Task<Result<'b,'c>>) -> 'a option -> Task<Result<'b option, 'c>>
// sequenceTaskResult: Task<Result<'a, 'e>> option -> Task<Result<'a option>, 'e>It could also be useful to have permutations that work with IcedTasks, such as:
// traverseCancellableTaskResult: ('a -> CancellableTask<Result<'b,'c>>) -> 'a option -> CancellableTask<Result<'b option, 'c>>
// sequenceCancellableTaskResult: CancellableTask<Result<'a, 'e>> option -> CancellableTask<Result<'a option>, 'e>Since there are a potentially large amount of possible permutations, I'm partial to breaking this into a few issues / PRs, but this at least gets the conversation started.
Describe alternatives you've considered
Custom extensions in each codebase that needs these functions
