Perhaps I am not writing idiomatic Julia, but I have immutable objects and from them I would like to construct new immutable objects with some fields modified.
Is there a simple way to do this? My current solution relies on reflection.: function copyImmutable(original, field, value) f = typeof(original) nama = names(Thing) args = ntuple(length(nama), i->if nama[i] == field value else original.( nama[i]) end) apply(f,args) end This relies on reflection and seems pretty clunky to me, there must be a simpler way. After all, returning modified parts of immutable objects is the bread and butter of functional programming.
