julia> NTuple{3}(zeros(4))
(0.0, 0.0, 0.0)

Is this intentional? I expected an error message. Cf eg

julia> NTuple{3}((1,2,3,4))
ERROR: MethodError: Cannot `convert` an object of type 
  NTuple{4, Int64} to an object of type 
  Tuple{T, T, T} where T

(tested on 1.10 and master, but this is not a regression, also the same in previous versions I checked)
