@dpo huge news, I successfully removed allocations from inplace broadcasted operations!!

using BenchmarkTools
using StatsBase
using PartitionedVectors

N = 5000 #elements
n = 20000
nie = 15
element_variables =
  vcat(map((i -> sample(1:n, nie, replace = false)), 1:N))

pv1 = PartitionedVector(element_variables; n)
pv1 .= 1
pv2 = PartitionedVector(element_variables; n)
pv2 .= 2
res = PartitionedVector(element_variables; n)

@benchmark res .= pv1 .+ pv2 .* 2

edit: I didn't implement what I taked yesterday about inplace basic operations for element vectors.
