(construct(::Type{T}, nodes::Tuple{Vararg{<:AbstractMultiScaleArray}}, args...)
where {T <: AbstractMultiScaleArray}) = __construct(T, nodes, eltype(T)[], args...)

(construct(::Type{T}, nodes::Tuple{Vararg{<:AbstractMultiScaleArray}}, values, args...)
where {T <: AbstractMultiScaleArray}) = __construct(T, nodes, values, args...)
gives:
ERROR: LoadError: Wrapping Vararg directly in UnionAll is deprecated (wrap the tuple instead).
You may need to write f(x::Vararg{T}) rather than f(x::Vararg{<:T}) or f(x::Vararg{T}) where T instead of f(x::Vararg{T} where T).
Stacktrace:
How do I handle this case?

wait, this signature was ever valid?

how is it supposed to choose between nodes and args?

The error message is unhelpful here since it's showing a random example rather than what you actually did. In this case you'd need nodes::Tuple{Vararg{T<:S}} where T, just put the where outside the tuple instead of only outside the vararg.

@Oscar Smith
can you help unblock this? I don't quite understand this.
