Thank you for the quick reply. I also tried
type
g = ref proc(i: int): g
Run
which compiles, but is not assignable
var x: g => 'Error: undeclared identifier g'
Run
A use case would be a simple state machine where the current state is
encapsulated by the function. This function returns another state function or a
null pointer. In C, it would be written like this
void *(*g)(int i)
Run
but it would be better to have a type
