f# - Accessing a member of JSON provider type -

i simplify following block of code rid of let expression

let jsonfeed = feed |> fbjson.parse jsonfeed.data  |> seq.head  |> ispromotion triggerinterval |> getdecision 

instead pipe way through right feed. how specify data member passed seq.head ?

this done lambda-expression:

feed |> fbjson.parse  |> (fun f -> f.data) |> seq.head  |> ispromotion triggerinterval  |> getdecision 

that said, don't understand desire rid of let. if you're worried polluting namespace, can hide within nested block:

let decision =    let feeddata = feed |> fbjson.parse     feeddata.data    |> seq.head     |> ispromotion triggerinterval     |> getdecision
