Confusing error message

julia> tmap(sin, 1:100; scheduler=:greedy)
ERROR: Greedy scheduler isn't supported with `tmap` unless you provide an `OutputElementType` argument, since the greedy schedule requires a commutative reducing operator.
Stacktrace:
 [1] error(s::String)

As a user, I never asked for a reduction.
