Re: [Caml-list] is there a more concise way to write this?

[Martin DeMello <martindemello@gmail.com>]

I ended up using

  let (>>?) x y = if x then [y] else [] in
  let a = (out   >>? ...) @
            (value >>? ...)

which had the advantage that it let me inline the definitions of o and
v while keeping things readable.
