I saw imperative sentences with the above-mentioned pattern with verbs "go", "come". The verbs are sometimes joined with "and". I understand it as informal usage with the first verb used as "encouragement" rather than "movement".
The question is:
- Can we use both patterns interchangeably?
- Can we use the to-infinitive as well?
- Can we use other verbs in this structure instead of "go","come"?
