ListOf cannot be required?

[justinbastress]

This code:

extension = SubRecord({
  "critical": Boolean(),
  "oid": String(),
  "value": Binary(),
}) 
relativeDistinguishedName = SubRecord({
  "type": String(),
  "value": String(),
})
certificate = SubRecord({
  "extensions": ListOf(extension, required=False),
  "raw_subject": ListOf(relativeDistinguishedName, required=True)
})

gives a runtime error TypeError: __init__() got an unexpected keyword argument 'required'.
