Documentation

data Value (s :: k)

Value that is independent of environment (Env) that produced it. Incidentally, this implies that it's "protected" against Emacs GC and thus will not unexpectedly go out of scope.

In order to prevent memory leaks, value is registered in the Emacs monad than produced it and will be freed when the monad finishes. To make the connection clear the value is tagged with parameter s, which serves the same purpose as tag of the ST monad. That is, it ensures that value cannot leave the scope of the monad that produced it.
