The standard F# idiom for this is the forward pipe operator |> were you would rewrite

let identifier = spaces_surrounded (many1Satisfy isLetter)

as

you can also use the backward pipe operator <| if you want to maintain the original order, but this tends to be a little less common

let identifier = spaces_surrounded <| many1Satisfy isLetter
