It is the best for performance in terms of the field types. If you
replace the `type` with `immutable` it might further improve
performance if you don't need to mutate it.

The type of `d` is stable (from this single assignment anyway) the
thing you load from it is not.

You need `Dict{AbstractString,Any}()` and no, narrowing down to an
abstract type won't help too much (and especially not for the key
type) `Dict{Any,Ions_frag}` should be much better.
