[julia-users] Re: Should `append!(a::Vector{T}, items::NTuple{N, T})` be defined in Base?
Interestingly, I have just noticed a bug in append!, see https://github.com/JuliaLang/julia/issues/15868 It occurs when you try to append a vector of elements which have a different type with respect to that of the original vector and when the conversion mechanism fails.

Considering the existing append! is pretty loose wrt the items being appended, a simple extension to the signature might work: append!{T}(a::Array{T,1}, items::Union{AbstractVector,Tuple}) You could extend this yourself to try it out.
