`type.reserved_field_name`

Field uses a reserved name.

Area 2, Values and types; not declinable; the next step is usually the agent's.

example

type Flag = Bool {}type Settings = Object {    optional: Flag}

jadpo checkcheck failed: 1 error, 1 file

error optional can't be a field's name

--> main.jadpo:4:5

  |4 |     optional: Flag  |     ^^^^^^^^ reserved

reason: include, pick, omit and optional are lines that build a type's fields, so no field may take their names.
next: Rename the field (agent)
