title: How can I use old style task names with the new gulp task api?
body: <p>According to <a href="https://gulpjs.com/docs/en/api/task" rel="nofollow noreferrer">https://gulpjs.com/docs/en/api/task</a> the new way to create tasks is not <code>gulp.task("xyz" ...)</code> but instead use <code>exports.build = build;</code>
  The problem with this approach is, that I can't use old task names like <code>feature:build</code>, <code>feature:watch</code> anymore, because I can only export valid JS identifiers.</p>
  
  <p>Is there any way to achieve this with the new method?</p>
