Passing an array to Gulp?

Question

JavaScript

Hello.
Got a question, got a code

const
    gulp = require('gulp'),
    $ = require('gulp-load-plugins')({
        pattern: '*'
    }),
    dir = require('./.conf/.dirrc.json'),
    pl = [
        $.pug({
            pretty: '\t'
        }),
        $.rename({
            extname: '.php'
        })
    ]
;

It's not running, it throws an error

Error: write after end

If the pl array is moved inside the task, then everything happens fine. The dev:watch:pug task calls dev:pug and rebuilds everything, if the array is in the global scope, be it let or const , it doesn't matter, using the pump plugin does not solve the problem.
gulp-pipe code:

module.exports = function pipe(stream, tubes) {
  tubes = tubes || stream.slice(1);
  return tubes.reduce(function(stream, tube) { return stream.pipe(tube); }, Array.isArray(stream) ? stream[0] : stream);
};

As I understand it, something happens when we pass an array from a common code to a function, I would like to understand
