Abstract
To address security concerns, a major change was introduced to the OCaml language and compiler which made strings immutable and introduced array of bytes as replacement for mutable strings. The change is progressively being pushed so that ultimately strings will be immutable. We have investigated the way OCaml package developers undertook the change. In this paper we report on a preliminary observation of software code from the main OCaml package management system. For this purpose we instrumented versions of the OCaml compiler to get precise information into the uptake of safe strings.
