Research direction

Start by reviewing the issue's vector-of-senders example and the constraints of the mentioned when_all facility. Determine whether the project already has an entry point for dynamically sized sender collections and what parallel execution and result collection should mean. Done should be a documented, agreed recommendation or a clearly scoped change request.

Written by the indexing model from the issue text.

Description

e.g. I have a vector of senders.

int n = <some runtime-known number>;

std::vector<MySender> senders;
for (int i = 0; i < n; ++i) {
  senders.push_back(...);
}

How to execute them in parallel and get all results? when_all doesn't work because all input senders of when_all should be known at compile-time. I can't pass a vector to when_all.
