(pipe-friendly) style.
When to use
Use to expose one implementation through both direct and pipe-friendly
call styles.
Details
Pass either the arity of the uncurried function or a predicate that decides
whether the current call is data-first. Arity is the common case. Use a
predicate when optional arguments make arity ambiguous.
Example (Selecting data-first or data-last style by arity)
import { Function, pipe } from "effect"

(self: number, that: number) => number
>(2, (self, that) => self + that)

console.log(pipe(2, sum(3))) // 5
Example (Defining overloads with call signatures)

(self: number, that: number): number
} = Function.dual(2, (self: number, that: number): number => self + that)
