This does not work with Gulp

[ehmicky]

get-stream does not currently work with streams created by gulp.src(), but that's a bug with Gulp, not get-stream. I am creating this issue for other people encountering the same problem.

gulp.src() uses vinyl-fs, which uses to-through, which uses streamx. streamx is a userland implementation of Node.js streams. Gulp currently uses vinyl-fs@v3, which uses an old version of streamx that lacks Readable[Symbol.asyncIterator]. vinyl-fs@v4 fixes this, but the latest Gulp (4.0.2) does not use that version.

In a nutshell, Gulp must upgrade vinyl-fs. They have not released in 4 years, but it seems like there has been some moderate activity latetely.
