I want to do parameter defaulting....
eg
I want to write something like blah x y = x + y
and blah x = blah x 0
ie...default y with 0 if it isnt supplied....
can I do this kind of thing?
Yes, you can do that provided you put the function as a (static) member of a class. Here is an example
type MyBlahStuff =
static member Blah (x,?y) =
x + (defaultArg y 0)
Ralf Herbrich (SniperEye)
that seems a bit ugly.....
perhaps I should explain more what I want to do....
I want a recursive function that takes a list and processes it. But I only want that function to go for a certain depth. So I figure I pass the depth through.... but I dont want the caller of the function to have to seed the initial depth what I want for general function call is
let rec blah l d = .... blah tail d+1
let blah l = blah l 0
type thing
How about:
let blah l =
let rec blah' l d = ...
blah' l 0;;
better..... but still a bit ugly :)
