Should not use labelled functions

[pbiggar]

As that is not idiomatic. It should instead by t-first (eg the List goes in the first position in functions in the List module)

[pbiggar]

Or maybe it should have a parallel set of modules that you can import that use labels. Simplest thing for now is no labels; we can always rescue the labels from the git history in the future

[pbiggar]

So this involves changing all the functions and tests so that the t goes in first place, removing labels

Eg:

let myFunc = (~count: int, ~sep:string, v: t)

would become

let myFunc = (v: t, count: int, sep:string)

The one exception is where there are multiple values of the same type:

let add = (a : int, b : int)

should become:

let add (a : int, ~addend:int)

to ensure they can't be accidentally misused
