[lucidrains]

hello! thanks for this great library!

i was wondering if you could possibly release this functionality

thank you in advance

In other words, the request is to create a new release. @treeform if you're busy we could help maintain the library.

Second the need for a new release. Just went to report an issue and realised it's fixed upstream but there hasn't been a release in two years

The fix is also incomplete:

type
  Frog = object
    leftLeg: Leg
  Leg = object
    length: int = 2

let s = """{"leftLeg":{}}"""
let f = s.fromJson(Frog)
doAssert f.leftLeg.length == 2 # fail; it's 0
