There have been a few situations where this would be useful, so I wanted to suggest it.

For example, a date range parser could be implemented as:

parseAsTuple([parseAsIsoDate, parseAsIsoDate])

Advantages over parseAsArrayOf(parseAsDate):

1. Ensures both dates are present.
2. Resulting type of [string, string] instead of string[] prevents certain type errors.
3. Elements could have different types (not relevant in this example).

Just an example there are obviously many others.
