Field value reference in validation

[rtritto]

With 2 query parameters allowed, at least 1 query parameter must be provided (required).

E.g.:

OK

• ?q1=v1&q2=v2
• ?q1=v1
• ?q2=v2

KO

• <NOTHING>
• ?q3=v3

Draft:

import { t } from 'elysia'

app.get('/', ({ query }) => {
  ...
}, {
  query: t.Object({
    q1: t.Optional(t.String(), /* true if q2 is provided (e.g. use q2 reference for condition) */),
    q2: t.Optional(t.String(), /* true if q1 is provided (e.g. use q1 reference for condition) */)
  })
})

Hi
I've opened a ticket because the validation schema works, but it's causing a TypeScript error.
