Will this PR be merged?
I'm needing the v-mask accepting array on a project and it would fit perfectly!

Btw, I tried to install the package using a reference to your commit, but it didn't work. Will it possible to do something like:
<input v-mask="['NNN-NNN', 'NNN-NNNN']"> for example ?

The inline array mask accepts an array of RegExp and strings that make up a single mask. It won't allow you to define multiple masks for the same input. For example:

<input v-mask="[/\d/, /\d/, /\d/, '-', /\d/, /\d/, /\d/]"> // '123456' => '123-456'

You could use a mask function to choose one of multiple masks though:

Vue.component('my-masked-input', {
  data() { 
    return { value: '123456' } ;
  },
  template: '<input v-mask="maskFn" v-model="value" />',
  methods: {
    maskFn(value) {
      if (someCondition) {
        return [/\d/, /\d/, /\d/, '-', /\d/, /\d/, /\d/]; // '123456' => '123-456'
      } else {
        return [/\d/, /\d/, '-', /\d/, /\d/, '-', /\d/, /\d/]; // '123456' => '12-34-56'
      }
    }
  }
});

This seems really nice. Would love to see this merged.

Wow! @davismcphee
This is awesome. I highly appreciate your effort.

I didn't have time to maintain the library actively for the last 6 months and it turned out there are a lot of nice stuff. I'll pull your PR and run all the check locally. There are also a couple of places not covered by tests. But besides from that MR looks really good!

Merged in #479.
Thanks again @davismcphee

@probil I'm happy to help. Thanks for the great library!
