Road to V2

I'm opening an issue for discussion about v2.

There is no immediate requirement for going forward a major release, but building some spec for v2 is a great way to ensure the new helpers to come, will respect standards until then.

Breaking changes in method signature:

• helpers with index (#579)
• helpers with callbacks:
  • #696
• helpers using lo.Entry type (#597)
• mutable helpers
  • #160
• variadic:
  • #224
• other bugs:
  • #788
  • #877

If you have any improvements in mind, please open an issue mentioning v2. I will add it to this list.
