import { fn } from "https://deno.land/x/ddu_vim@v4.0.0/deps.ts";
const { and } = fn;
Bitwise AND on the two arguments. The arguments are converted
to a number. A List, Dict or Float argument causes an error.
Also see or() and xor().
Example:
:let flag = and(bits, 0x80)
Can also be used as a method:
:let flag = bits->and(0x80)
