CoCaml is a strongly-typed call-by-value functional language in the ML family. It is syntactically almost identical to OCaml, except that variables are mutable (can be rebound) as with the Scheme set! construct. This is done to give a uniform semantic treatment of recursive functions and coinductive datatypes. An added benefit is that it also supports familiar imperative constructs.
CoCaml is based on the semantic concept of capsules, a heap-free semantic model for functional and imperative programming. The theory behind capsules is described in the references below.
