but is it alright to use stmt here?

shouldn't this be

Cil.get_kernel_function (Cil.copy_visit ()) (Extlib.the self#current_kf)

as the type is

val get_kernel_function : visitor_behavior -> Cil_types.kernel_function-> Cil_types.kernel_function

Also, what does this function do? Does it construct a new kernel function?
