Is there a built-in function to get the length of a tuple as a Val{N}? Basically I’m looking for something that would be of the form: tuplen(::Type{Tuple{}}) = Val{0}() tuplen(::Type{Tuple{T}}) where T = Val{1}() tuplen(::Type{Tuple{T1, T2}}) where {T1, T2} = Val{2}() tuplen(::Type{Tuple{T1, T2, T…

Yup–it’s actually a simple one-liner: julia> tuple_len(::NTuple{N, Any}) where {N} = Val{N}() tuple_len (generic function with 1 method) julia> tuple_len((1, 2, 3)) Val{3}() julia> tuple_len((1, "hello", π)) Val{3}() julia> tuple_len((1, "hello", π, [1])) Val{4}() This works because tuples (unl…
