In v2.4.4, +(date/timestamp/array/map) are valid, we should add a migration guide for these.
In v2.4.4 and master, +(string) with integrals returns integral, but -(string) with integrals is coerced to double. we seem to need a migration guide too even through.
In v2.4.4 , bit-string constants with x-prefix is not supported yet.
