Goal

Allow for alternative syntax for nested variants.

Description

Nested variants are currently hard to write and result in some repetition. ICU's experience with MessageFormat also suggests that it is easier for localizers to work with full sentences as variants.

The proposed solution is to allow lists as selectors in select-expression and as variant keys:

key = { $items, $buckets ->
  [one, one]     Found 1 item in 1 bucket.
  [one, other]   Found 1 item in { $buckets } buckets.
  [other, one]   Found { $items} items in 1 bucket.
  [other, other] Found { $items} items in { $buckets } buckets.
}

Dependencies
