Is it possible to run local commands in parallel?

[trsteel88]

Wondering if there is a way in v7 to run local tasks in parallel.

e.g. when we deploy we validate the repository is in a pristine condition (up to date, no uncommitted files, on branch that is being deployed), dispatch a notification to 2 different services, build assets.

It would be great if all 4 of these tasks could be run in parallel to speed up deployment. Is this already possible?

Currently it's not easy to do, as you need to use something like this:

// Hosts

host('example.com');
localhost('build');
localhost('notify');
localhost('verify');

// Tasks

task('build', function () {
    if (currentHost()->getAlias() === 'build') {
        run('...');
    } else if (currentHost()->getAlias() === 'notify') {
        run('...');
    }
})->select('alias!=example.com');


before('deploy', 'build');

task('deploy')->select('example.com');

And build will be parallel:

❯ dep deploy all --plan
┌──────────────────────┬───────┬────────┬────────┐
│ example.com          │ build │ notify │ verify │
├──────────────────────┼───────┼────────┼────────┤
│ -                    │ build │ build  │ build  │

But this is not really nice. I'm gonna think about adding special ->parallel(); method for a group task.
