Curry and Pipe/Compose incompatibility

[millsp]

I took these straight from the examples and the curried function inside compose is throwing an error.
The curried function has the correct type.
The composed function works without the curried one.

declare const compose: Function.Compose
declare function curry<Fn extends Function.Function>(fn: Fn): Function.Curry<Fn>

const a = curry((a1: number, d2:  number) => `${a1 + d2}`)
const c = (c1: string[]) => [c1]
const b = (b1: string) => [b1]

compose(c, b, a)(23,42)

You can try it in the ts-toolbelt codesandbox:
https://codesandbox.io/s/ts-toolbelt-x4jly?file=/src/index.ts

The error:

const a: Function.Curry<(a1: number, d2: number) => string>

Argument of type 'Curry<(a1: number, d2: number) => string>' is not assignable to parameter of type 
'Function<[a1?: number | x, d2?: number | x], string>'.
  Type 'Curry<(a1: number, d2: number) => string>' is not assignable to type 'string'.ts(2345)
