Hi,
I am trying to model a situation in which a caller calls a combination
of two functions:
- The first is a postprocessor that depends on the invocation g: a -> 'b
- The second is a higher order function: f: c x d x g -> 'b
One could leave the application of 'g' to the caller, making f: c x d -> a.
Then the caller would run:
let res_a = f inp_c inp_d in my_g res_a
But it would be nice to hide 'a' from the caller and have her call:
let res_b = f inp_c inp_d my_g
I guess I could use functors, and configure a generic f with a
particular type of g. Does that seem right, and if so could there be a
simper or easier way?
Sen
