Not a direct answer to your question but you could look at Reason. It is a C style syntax that layers on top of the OCaml semantics. Writing in Reason is writing OCaml. However, the new syntax makes it more approachable for people coming from C style languages and removes idiosyncrasies like the double semicolon.

Its still progressing and more focus has been given to getting it up and running in a compile to JS context but it should be equally as capable of systems work, especially as time goes on.
