Add splice! for StructArrays?

[sairus7]

At a first glance, this seems to work. But maybe there are other corner cases or more performant versions...

using StructArrays

function Base.splice!(s::StructVector{T}, index::Integer, vals=T[]) where T
    valsT = StructVector(vals)
    t = map((v, val) -> splice!(v, index, val), StructArrays.components(s), StructArrays.components(valsT))
    return StructArrays.createinstance(T, t...)
end
function Base.splice!(s::StructVector{T}, indexes, vals=T[]) where T
    valsT = StructVector(vals)
    t = map((v, val) -> splice!(v, indexes, val), StructArrays.components(s), StructArrays.components(valsT))
    return StructVector{T}(t)
end

a = [(1,'a'),(2,'b'),(3,'c')] |> StructVector
new = (0,'x')
splice!(a, 1, [new]) == (1, 'a')
splice!(a, 1:0, [new,new]) |> isempty
splice!(a, 4:5) == [(2,'b'),(3,'c')]
a == [(0,'x'),(0,'x'),(0,'x')]
