OK thanks John, I ended up doing a bit differently but it works fine. Sorry
to keep asking, but now I have another problem I can't seem to wrap my head
around: consider
my_type_collection = Vector{MyType}
my_type_collection[1] = MyType(a,b,c)
returns: `setindex!` has no method matching
setindex!(::Type{Array{MyType,1}}, ::MyType, ::Int64)
Seems a bit weird to me, since
my_type_collection = [MyType(a,b,c); MyType(d,e,f)]
my_type_collection[1] = my_type_collection[2]
works just fine.
