Easy way to skip fields of an object

[Cameron Reikes]

Say I have an object like this:

  Player = ref object
    username: string
    ready: bool
    conn: WebSocket
    curLevel: JsonNode
    invadingUsername: string
    heistSuccess: bool
    id: uint64

that I want to dump to json, but don't want the conn to be in the dumped json. What if jsony had some kind of skipHook you could define to describe what fields to skip serializing?

Beef on the discord advocates for a skip pragma like this:

import std/macros
...
for name, field in object
  when not field.hasCustomPragma(jsonSkip):
    ## serializer

and a template like this: template jsonySkip*{.pragma.} with conn {.jsonySkip.}: WebSocket
