Is your feature request related to a problem?

Currently, no error is shown here:

pipeline test{
    val a = [g()];
}

fun g() -> (r: Int, s: Int)

But calls that produce multiple results must only occur as

  1. the RHS of an assignment, or
  2. the receiver of a member access.

Desired solution

Add validation. Ideally, avoid overlap with errors from the type checker.

feat: type checking for list & map literals (#751)
dc14223 
Closes #712

### Summary of Changes

Don't allow calls that produce no or multiple results inside list & map
literals. In other cases, the existing type checking already took care
of this.
